Object discrimination and optical performance of a real-time 2-5 μm hyperspectral imager

摘要

Hyperspectral imaging in the 2-5 um band has held interest for applications in detection and discrimination of objects of interest. Real time instrumentation is particularly powerful as a tool for characterization and field measurement. A compact, real-time, refractive MWIR hyperspectral imaging instrument has been designed and tested. The system has been designed for cryogenic operation to improve signal to noise ratio, reduce background noise, and enable real-time hyperspectral video processing. The system is a a 2-5 μm 32-band hyperspectral imager capable of collecting and processing complete hyperspectral image cubes at 15 cubes-per-second. Details of the system and object discrimination using this system are presented.
