ABSTRACT:
A hand-held, fleet deployable infrared camera with integrated hardware and software providing real time processing of infrared images. The camera senses variable temperature images over a selected object of interest and senses variable emissivities over the object. The camera also measures and corrects for reflected environmental radiation as well as corrections for the atmospheric path through which the object is viewed. A calibrated reference patch having known emissivity and reflectance is attached to an object of interest and viewed through the camera. The calibrated patch is used to provide correction for the environmental radiation reflected off the object. Once the environmental radiation correction is known, it can be used to correct measurements taken from the rest of the object of interest.
