InGaAs experts modify customer designs for better performance and yields.

Michael J. Lange, Sensors Unlimited Inc.

InGaAs short-wave infrared imaging is growing rapidly. In military circles, it is emerging as a complement to thermal imaging for covert surveillance, fire control and training, and as the ideal solution for eye-safe laser imaging. In commercial applications, it is enabling machine vision systems and medical devices to see what other imagers cannot. Sales of InGaAs short-wave IR detectors and imagers are rising much faster than the 8 to 10 percent growth rate for imaging as a whole, with the increases splitting about evenly between commercial machine vision and military surveillance. The...Read full article

    thermal imaging
    Thermal imaging is a technology that detects infrared radiation (heat) emitted by objects and converts it into an image, known as a thermogram, which displays temperature variations in different colors. Unlike visible light imaging, thermal imaging does not require any ambient light and can be used in complete darkness or through obstructions such as smoke, fog, and certain materials. Thermal cameras use sensors to detect infrared radiation and generate images based on the temperature...
