MIT researchers have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once, something never before available to integrated ...
Tunable optical filters lie at the heart of modern spectroscopic instrumentation, enabling selective transmission of narrow spectral bands with dynamically adjustable centre wavelengths. Key ...
Imaging equipment to observe the earth from space provides data for various uses. Wavelength-discriminated imaging at a considerable distance from the earth’s surface is the basic idea behind optical ...
