In December last year, Magic Leap One released the first version of its Magma Leap One creator for the first six years of preparation, and wrote after the experience of the Rolling Stone reporter that its realistic virtual objects are opaque and can be obscured by real objects , Making people difficult to distinguish.This effect is shocking, however, because the product is not listed, we do not know how the optical display of Magic Leap exactly how to achieve.
Magic Leap official description said: Our light field photons produce different depths of digital light and seamless integration with natural light, which will be lifelike virtual objects superimposed in the real world. Magic Leap initially announced that they used a fiber scanning light field display Technology (FSD), a photon optical field that resolves the problem of visual convergence by focusing / depth planes, and a diffraction waveguide called a "light field chip." These technologies, Magic Leap, have been kept secret, with little knowledge of the industry.
Lei Feng Network learned that a patent document (No. 2017/0276948) last year showed that Magic Leap did not adopt an optical fiber scanning light field display technology that was difficult to achieve. Instead, it chose the LCoS display solution. However, it remains unclear how Magic Leap's optical display technology is implemented.
March 2, according to foreign media Next Reality reported that the United States Patent and Trademark Office also announced a number of patents from Magic Leap patents, including the structure of the Magic Leap, system methods and waveguide display principle.
A patented document titled 'Virtual, Augmented Reality and Mixed Reality Systems and Methods' (click to download) contains highly detailed drawings of Magic Leap One's headwear, Lightwear, Computing Center Lightpack and controllers, These drawings are almost identical to the ones we have seen so far, allowing us to learn more about the structure and design of the Magic Leap One.
Another patent, entitled 'Multilayer Diffuse Eyepieces' (click to download), describes how Magic Leap's 'waveguide display' works. According to the description, there is a grating behind the waveguide, a wavelength selective reflector, and the image is projected through the waveguide To the user's eyeglasses The grating directs the light from the waveguide to two different directions At the same time the reflector reflects a portion of the light from the second direction back to the first direction.
Lei Feng Network understands that the patent document also describes that Magic Leap One's eyepiece has three such waveguides and is capable of producing three wavelength ranges, each corresponding to red, blue, and green light, and then reflecting the light in multiple Region as described in the previous patent for system and method interpretation, the wavelength can produce three fields of near-field, mid-field, and far-field, as described in the system and method patents.Virtual objects Displayed between light fields and mixed between light fields to give depth illusion.
At a recent Code Media conference, Magic Leap CEO Rony Abovitz said, 'We want to interact with your visual cortex in a very biological way, which creates a lot of amazing experiences. We spend a lot of energy and money The establishment of the 'Digital Light Field', after millions of years of evolution, has changed the eyes of our creatures to the present, all related to how light interacts with the creatures. '
Although Magic Leap has repeatedly publicized the wonders of its products, only a few have experienced its products and are only vaguely described by non-disclosure agreements.
