A compact yet robust sensor system for applications in harsh environments has been developed. The sensor takes advantage of infrared attenuated total reflection (IR-ATR) spectroscopy with an invariant ...

The Active Ir Sensors Market encompasses devices that emit infrared radiation and detect its reflection to measure distances, detect motion, or identify objects. These sensors play a critical role in ...

Abstract: With the rapid development of intelligent identity authentication technology, features used for identity identification are gradually increasing, but some of the existing identity ...
