The uncooled Thermal Imaging Radiometer (TIR) utilizes a single microbolometer detector array to obtain calibrated infrared images in four spectral bands. The spectral bands and bandwidths are user selectable from 8 to 12 microns. The TIR is a portable system designed for both indoor and outdoor use. It is controlled by a laptop computer which also displays the fully calibrated spectral images in real time with both color and gray scale options. The TIR scans 360 degrees and provides continuous imaging of the surrounding scene on the laptop display. Selected images can also be saved for radiometric analysis. Early test results and thermal images from the TIR will be presented.
