Optics technologies are only viable if they can be produced with high quality at scale. To provide an AR platform that businesses can rely on to get work done, we needed to reproduce our optics advances at industrial scale, while always maintaining image quality -- fabricating tens of thousands of eyepieces, quickly, reliably, and without defects.
Since HDR stands for high dynamic range, an HDR display needs, well, high dynamic range. This is easy for certain technologies, like OLED, which has a near-infinite contrast ratio and lots of brightness. It's also a cinch for many LCDs with local dimming, which gives them a better contrast ratio and therefore a wider dynamic range.
All projectors use one of three technologies: DLP, LCD, and LCOS. LCoS, available in projectors made by Sony and JVC, has the best contrast ratio of any of the projector techs, but even it falls far short of what OLED and local dimming LCDs can do. DLP and LCD, which together make up the bulk of the home projector market, don't have anything close to the contrast ratio of even D-ILA. Lacking the area-dimming contrast ratio enhancement of local dimming of LCD TVs, there just isn't the dynamic range available to make any use of HDR content.
A black body source is particularly useful for developing new technologies that deal with thermal imagery because they deliver consistent and expected results. The black body radiation they produce is well behaved and in accordance to the parameters that the developer sets.
When developing a new method of thermal imaging, this allows for the accuracy of the technology to be tested to values as accurate as the black body radiation source will allow.
The main reason accuracy is so important revolves around the delicate nature of military electro-optical technology. A greater range, such as the -40ºC to 1200ºC range that the black bodies from CI Systems provides, allows for imaging technology designed to find man-made installations in extremely cold climates to developing optics capable of being used with satellites to inspect for weapons of mass destruction.
The accuracy of these machines to produce black body radiation influences the results that the developer can expect. This helps to eliminate false positives while ensuring the technology can accurately determine valid results.
A modern heads-up display (HUD) for automobiles uses triple laser-diode pico projector solution for infinite focus, readability in sunlight, superb color, and small size. An automotive, triple laser-diode pico projector system on a chip (SoC) is built around a pico laser driver. This bridge-chip solution reduces size, cost, and design complexity for automotive HUDs.
The newest HUD technology is implemented by moving MEMS mirrors and color lasers, also known as pico laser projectors. These laser projectors have infinite focus, readability in sunlight, superb color saturation, and small size, all of which make them an ideal medium for the automotive infotainment environment.
LCDs, DLP, and other backlit technologies are challenged by nighttime and tunnel conditions where backlight leakage can create shadows and ghost images. This is not an issue with laser projectors, as the lasers light each pixel with a front-light approach. Since laser projectors add light on a pixel-by-pixel basis, except for laser bias current, power is always less than 100% full on. The power can be turned off during blanking and when the pixels are black. In this way power consumption is reduced to 80mW for an all-black scene. The MAX3601 has a multiplier DAC that can safely modulate the light output power from 1 lumens appropriate for darkness all the way up to 30k lumens in bright sunlight.
Laser colors are continuously monitored to ensure a consistent color over a wide variety of temperatures and to ensure safe laser conditions. Color sensors are also used to compensate for brightness under daylight, shade, or nighttime conditions. Since the laser is always in focus, complex and costly optics do not consume valuable space in a light engine. Consequently, the laser projector fits into the tightest of spaces in the smallest of vehicles. Because today's HUD architecture uses seven or more devices for this color presentation, the space that it saves becomes exponentially more valuable.
Although the foundational problems with immersive light displays were solved more than 20 years ago, more recent improvements in technologies, like projectors, have vastly improved the quality of the experience for the viewer. Projectors are now the optical muscle behind many large immersive art installations. Technological advances have made them brighter, more colorful, longer lasting, and more energy efficient, but fundamentally they work as they always have: a light source, an image source, and optics to focus and project the results.
The XW7000ES utilizes many of Sony's popular features and proprietary technologies discussed in great detail in our reviews of other Sony home theater projectors including the VW1025ES, VW915ES, and VW715ES.
The new SXRD panel offers higher light and a flatter reflective surface which improves the XW-Series brightness and native contrast. While the new SXRD panels offer very high native contrast, the XW7000ES projector's dynamic contrast is nearly infinite due to their ability to precisely modulate their laser light sources.
The OpTest Lens Measurement System has been completely redesigned by Optikos engineers to include the latest technologies and innovations in optical and opto-mechanical engineering. Other products on the market compromise by manufacturing their systems around general purpose off-the-shelf lab components, while every step of an Optikos solution is a custom one. OpTest systems are composed almost completely of custom optics, mechanics, and electronics designed by Optikos engineers solely for the purpose of lens testing.
A 3D projector is a device that projects images in three dimensions. It uses a combination of technology and optics to create a realistic 3D image. 3D projectors use active shutter glasses to create a 3D image that can be viewed with the naked eye.
A 3D-ready projector is a projector that is capable of displaying 3D images without the need for special glasses or a special screen. It uses a combination of technology and optics to create a 3D image.
A 3D active projector is a projector that is capable of displaying 3D images with the use of special glasses and a special screen. It uses a combination of technology and optics to create a realistic 3D image.
