Uncooled infrared detector designed for Gas detection and High temperature measurements

摘要

Uncooled infrared focal plane arrays are being developed for a wide range of thermal imagingrnapplications. A new type of detector for middle and long wave applications was developed based onrnamorphous silicon VGA device. This new detector is well adapted for gas detection, highrntemperature measurements, and special industrial processes (boiler control and maintenance). Afterrna brief introduction to microbolometer technological background, the interest of such detectors will bernpresented by comparing LWIR / MWIR detector signal to noise ratio, and the advantages for differentrnapplications will be highlighted. Finally, the main electro-optical characteristics and performances willrnbe presented.
