The article is not a paper, however an overview that understands easily. Provide the basic understanding of pair of wave guide markets for the reader, how does the progress that yields a reader to feel optical territory change structure of intelligent glasses market slowly.

 

Close eye learns ABC

 

The person of glasses of most familiar intelligence is met to the video that uses in GoogleGlass have roughly understanding, its structure is very simple: Jacket of equipment of glasses lateral electron has video of a miniature (specific is LCD of a silicon radical) , of this miniature monitor give what light points to a 90° to turn to prism, lend the right upper part of the person that this can project indication beam of light glasses adorns eye shot. Below this kind of circumstance, miniature monitor and prism component formed an optical unit, following plan institute are shown, this optics combines unit by wonderful view photoelectricity (HiMax, the factory of OEM of an optical component that comes from Taiwan) supply.

 

 

Now, imagine such two 90° turn to prism and the platoon is placed, following plan institute are shown. What such prism setting can show miniature video to image rotates 180° , OK also the or so deflection that roll realizes indication image to go up in same way among them. Here, we are revealed with the simplest form, this one effect considers on parts of an apparatus of smooth wave guide when us when, this kind shows changing direction can be an important principle.

 

 

ABC of smooth wave guide

 

Itself of smooth wave guide is not a new technology, the monitor that is based on technology of smooth wave guide uses same technology to make, it allows one-way light-wave edge fiber-optic transmission. Look from flank when you fiber-optic when, you cannot see the light, and can see the spot that comes out finally only. This kind of character that light-wave guides lens uses one-way light wave likewise will guide light-wave to pass lens or plane to ground of other one aspect of the matter from one aspect of the matter (planar wave guide) .

 

LumusOptics (the martial industry that comes from Israel studies) most commercialized a few the mainest light wave to guide first, it also becomes the OEM supplier of Daqri and Atheer recently.

 

 

Gu Ge and all alone Buddhist nun own as similar as design of smooth wave guide patent. The Optivent company of wonderful view photoelectricity and Lumus and France, Essilor company of Lumus and France finished the research of projects of a series of smooth wave guide jointly. Among them, essilor is the biggest lens manufacturer on the world, recently the Luxottica that the as biggest as the whole world spectacles wears company Italy is amalgamative.

 

Light-wave of ” of “ surface anaglyph guides (Surface Relief Waveguides)

 

To design of more complex smooth wave guide, imagine the prism above narrows very small size, be spun again next. A series of these prism are carved in camera lens surface now, these small backbone are called smooth wave guide of ” of “ surface anaglyph. Use this kind of smooth wave guide, the picture that miniature monitor shows can be broken up a series of perpendicular stripe, these stripe that contain image information are met by lens other one aspect of the matter (be located in eye ahead) a corresponding group of small backbone are assembled afresh and cast to the eye.

 

 

Technology of smooth wave guide of ” of anaglyph of surface of this kind of “ is the earliest the patent that is Nuojiya, also commercialize by Nuojiya later. The smooth wave guide that uses in the HoloLens of Microsoft used this kind of design, nevertheless Microsoft was made to its revise, they design crust erect condition, and miniature monitor is designed in eye upper part.

 

Nuojiya’s patent is very notable, had been proved what dimensions turns production to be OK because of it. Not only such, besides HoloLens, nuojiya still gave Vuzix this design authorization, latter is in a factory that aids financially by Intel investment to produce corresponding smooth wave guide, associate in order to mix cooperative brand sells Chinese business market.

 

The inspiration that other company also got ” of anaglyph of surface of this kind of “ is designed, finnish Dispelix company produced light-wave of ” of “ surface anaglyph to guide not only, and still made significant contribution for workmanship. Dispelix expresses, besides be similar to Nuojiya (subtration is made) besides wave guide of ” of anaglyph of sculpture “ surface, still can add craft through adding (addition is made) form small backbone, presswork through “ for instance the means of ” accomplishs small backbone camera lens to go up.

 

Magic Leap

 

 

To Magic Leap a such private companies, a few information are obtained in we can apply for from their patent and be being bought, for instance, when the product is being rolled out before them, had not decided its implementation wishs the method of scene.

 

MagicLeap to find a kind can the method of monitor of mass production smooth field, had tried all sorts of optical designs. Smooth field can produce result of depth of field, make look clear at focal object, the object of position of focus of and rather than can blur. For the recreational application that seeks to Magic Leap place, smooth field technology is OK more bona fide presents fictitious content.

 

Last year in April, abovitz published the title page of a thread-bound book of Wired magazine by right of ” of chip of Magic Leap“ photon. One word of “ chip ” is used in the name of this magazine quote, this also divulged they use those who make the video with this kind of academic very strong sex to produce a method.

 

MagicLeap at 2013 – 2014 year during referred patent discussed all sorts of peculiar optical designs, these design more are ” of be an armchair strategist of a kind of “ , its norms had exceeded existing technology engineering capability. The monitor that although can make a Magic Leap now,puts forward in one of series patent, they still face two large block, the first it is cost: The CPU with the contemporary area ratio of glasses lens is auspicious and severalfold, and a whole intelligence shows glasses needs a pair of lens more. This is meant, although Magic Leap can make a such video, the camera lens that this kind of monitor place uses makes cost (every reach thousands of dollar to also be being met) also can let a person flinch, and the dimensions economy effect that the company place that they also lack so mass-produced like Intel chip enjoys. Next, the monitor that involves in these patent application is in with lens ply 1 to 1.5 centimeters between. What Magic Leap aims at is consumer market, although they can be made,give such product so (although ignore,make cost even) , so thick close look shows the product also cannot have position in consumptive market.

 

Here, magic Leap returned phase of first draw drawing board again it seems that. Their patent still included what light-wave of ” of anaglyph of surface of a few “ guides to derive plan, for instance light-wave of ” of anaglyph of surface of cascade type “ guides. This lets us think of again in front the pressworking that Dispelix uses is small backbone technology.

 

Last year, magic Leap bought a company that the name is MolecularImprints sadly. As identical as Dispelix, the patent technology of this company also can realize small backbone to presswork.

 

This kind is based on presswork cascade small backbone of the technology can offer a kind for MagicLeap well can with thin model the smooth wave guide that the structure produces smooth field to show, and still can reduce production cost but susceptive limits. But Dispelix has begun production to presswork smooth wave guide of ” of anaglyph of type “ surface, and Avegant is more video of a smooth field was shown recently (the component that used a convention bundle implement technology) , accordingly. This kind of products plan of Magic Leap may have lost a lot of novel sexes.

 

Holographic wave guide

 

“ is holographic the “ in wave guide ” is holographic ” is not the image that shows the person that adorn sees in front of them, point to the optical parts of an apparatus inside camera lens however, their itself is made by hologram of accept rice class.

 

Think the hologram that you see on credit card. On the reflection back line of credit card sticky stuck a piece of film, there is the hologram that forms through exposure means on this piece of film (the reflection back line at the back of credit card hologram is used at be hologram to offer to reflex type illuminant) .

 

To holographic for smooth wave guide, its production method and the hologram above are similar–Form the hologram of accept rice class of parts of an apparatus of lens shape optics through stimulating smooth exposure to be inside filmy light polymer, the filmy smooth polymer here is embedded inside lens, the action in can replacing prism to guide in traditional light-wave. To it before same, miniature monitor projects the one aspect of the matter of camera lens, direction of beam of light of roll of holographic and optical system, guide one-way beam of light to pass the surface, another group of structure criterion change these beam of light to the eye further. The ply that the project technology place of this kind of creativity realizes has original prism type only a few of plan of smooth wave guide.

 

Nearly 10 years ago, digiLens undertook improvement to this kind of technology, it is American army (with Luo Kewei Er Collins company cooperates) compose built aviation HUD system, these systems still belong to a secret at present.

 

A few are based on recently holographic the product of technology of smooth wave guide: British TruLifeOptics and WaveOptics, and the Akonia Holographics that division collect helps much city. Had gone up in this kind of technology before Akonia spent 10 years of time, and be in investment is holographic the loss is returned when memory 100 million much dollar. These 3 companies appear to had been revealed below lab condition now be similar to DigiLens 2010 year design.

 

 

All in front design of mentioned smooth wave guide still belongs to lens of “ passive ” . Passive camera lens itself does not have electronic component, they just receive the light with miniature projectile monitor, guide the light passively to cross camera lens, turn to project finally backward in the eye of the user.

 

Active is holographic wave guide

 

DigiLens design gives “ active ” is holographic smooth wave guide.

 

Through using the filmy polymer that is based on liquid crystal, inside DigiLens smooth wave guide holographic condition of the change when parts of an apparatus of lens shape optics is using electric current to activation.

 

 

From begin the earliest with monitor with Yu Jun, digiLens all the time take root is in aviation electron domain. They cooperate with company of Collins of Luoke Wei Er again, begin to found the monitor that is based on technology of smooth wave guide on the jet of company of Brazilian aviation industry, installation of this kind of monitor is on dashboard. The first their consumer goods, namely monitor of BMW intelligence helmet, will this year later on put on sale.

 

In addition, the technology of smooth wave guide that mentions in front is by the tie on even plane. Some earlier this year moment, digiLens still announces they had perfected active holographic the wave guide application in surface of curved surface lens, this means them to be able to go to these technical application on common glasses. They just ended to be mixed by Suo Ni recently Fuji health the financing of round of of collective leader 22 million dollar.

 

Be opposite recently DigiLens author, president, presiding apparitor holds chief technology officer Dr. Jonathan Waldern concurrently in interviewing, he still divulges the company is studying use He Guangbo guides the technique with similar monitor, use layer pressing plate at camera lens interior (what here cancels is camera is not small monitor) , with similar light body fact lose face eyeball dogs.

 

Show some products plan at DigiLens relatively, the novel sex that this kind of new design brings may remain smooth field technology only. If say Magic Leap is being passed,use multilayer if structure of smooth wave guide implements smooth field technology, this used to plant in the design that DigiLens has had in them multilayer technology of smooth wave guide: Will gules spectrum departs and guide enter corresponding smooth wave guide, the coping that wave guide of this corresponding flashes of light preceding an earthquake guides in glaucous light-wave. In addition, digiLens still uses smooth wave guide to hand in fold plan to expand visual field. If they had not used this to plant statified technology of smooth wave guide will realize smooth field to show, because their client has not raised this kind of requirement,that is – they up to now dedicated all the time is text navigation data, is not recreation. If pay cost client to raise the requirement that smooth field shows, we can decide DigiLens can be used certainly those who have is statified technology of smooth wave guide.

 

DigiLens is a sleep deeply alone horny animal, it is compared in this domain other OEM of any smooth wave guide are advanced at least 7 years. Although DigiLens is the same as the collaboration of American military side to still may belong to a secret, but should know American army is building what kind of HUD to still won’t violate safe regulation, all the time the video technology of use DigiLens makes this kind of HUD makes them.
