Driven by Lumus' patented Light-guide Optical Element, a micro-display pod, and the Optical Engine which projects light into the lens -- where it is reflected back to the user's eye via reflectors embedded in the lens -- the Lumus' DK-32 delivers a bright 720p 3D-capable display that only weighs 27 grams.
The universe is pretty transparent to optical light--that's how we can see far away galaxies.
There are many older optical fibers, but low-light-loss ones are vital for telephone cable.
Gamma-rays are the most energetic form of light, with wavelengths far shorter than ordinary optical light (the light your eye can see), or even ultraviolet or X-ray light.
The content zooms and clatters over an array of archaic and futuristic gear, from aging copper phone lines to light-bending optical switches.
The only instruments capable of measuring such vibrations, though, were spectroscopes--meter-long glass-and-metal optical devices that used infrared light.
The only instruments capable of measuring such vibrations, though, were spectroscopes--4-foot-long glass-and-metal optical devices that used infrared light.
An optical mouse uses a beam of light and an optical sensor to detect movement over a surface -- there are no moving parts.
This is the wavelength of the infra-red light normally used in optical communications.
All-optical routers that can manipulate packets of light, pulling some signals off a fiber and sending the rest on their way, may not be widely available for years.
The WB800F is a classic long-zoom camera, with 21x optical zoom and a 16.3 Megapixel BSI CMOS sensor for excellent low-light photography.
ENGADGET: Samsung launches six new point-and-shoot cameras at CES
The mirror-less camera builds on its forbears, phasing out the mirror-based optical viewfinder of the SLR camera and adding an interchangeable lens mount, while keeping the light-weight feel of the compact camera.
Infrared light is used mainly for optical communication--including for sending messages between a remote control and the TV.
Sometimes, these rotations bring big payoffs, such as when 3M realized that the problem of laptop battery life was really a problem of energy used up too quickly for illuminating the screen. 3M researchers applied their knowledge of see-through adhesives to create an optical film that focuses light outward, producing a screen that was 40% more efficient.
Another example involved creating "light pipes" as a 3D-printed alternative to optical fibre.
Optical lithography techniques become increasingly problematic as engineers build tinier devices--the wavelength of the light used to cast patterns onto silicon is already bigger than the width of the devices engineers want to create.
The galactic centre can only be observed at certain wavelengths - such as X-rays - because large amounts of dust lie in our line of sight, blocking out optical light.
It's the first handset to feature optical image stabilization -- the floating sensor and lens enable ultra-stable video recording and phenomenal low-light stills.
