University of Wisconsin-Madison scientist develops a new pin-sized sensor that can detect dangerous chemicals

The scientists at the University of Wisconsin-Madison in the US have developed a novel sensor that can be used in smartphone-sized devices to detect dangerous chemicals based on a unique fingerprint of absorbed and emitted light. Devices called spectrometers are light-splitting instruments that have long been both bulky and expensive, preventing their use outside the ..

ISRO to launch a full-fledged niche Earth observation (EO) satellite “HySIS” to enable distinct identification of objects from space

ISRO will soon launch a full-fledged niche Earth observation (EO) satellite called the Hyperspectral Imaging Satellite (HySIS) by using a critical chip it has developed. The purpose of the HySIS satellite is to enable distinct identification of objects from about 600 km in space. The Vis-NIR Hyperspectral payload of HySIS satellite is a hyperspectral imaging ..
