Hyperspectral imaging in the 2-5 um band has held interest for applications in detection and discrimination of targets. 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 is undergoing integration and test. The system has been designed for cryogenic operation to improve signal to noise ratio, reduce background noise, and enable real-time hyperspectral video processing. Partial testing has been completed on cryogenic elements and “first light” 2-5 μm hyperspectral images have been collected at room temperature.
