Night-Vision Camera Combines Thermal and Low-Light-Level Images

Tags associated with this item:Even on moonless but starlit nights, highly sensitive InGaAs cameras still produce good images for short-wavelength infrared. By thinning the image sensor chip and with illumination right through the substrate, the wavelength range of the detectors can be extended into the visible spectrum to then span 400 – 1700 nm. Together with uncooled microbolometer arrays for long-wavelength infrared, this allows the design of universal analysis tools which can take advantage of the fusion of optical and thermal images.
From micro to macro: NIR sensors and imaging spectroscopy - a perfect match
Submitted by XenICs NV on Mon, 04/07/2008 - 14:46. Tags associated with this item:Image capture in the near-infrared spectrum (NIR) at wavelengths up to 2.5 um is gaining ever greater economic significance. This is especially true in regard to imaging spectroscopy: hyperspectral microscopes, for example, can accelerate the design process of new kinds of LED structures; multispectral online inspection of recyclable materials ensures unmixed waste separation; and finally, in the arts, multispectral reflectography serves as a tool revealing the secrets of old masters and their works.
