An imaging radiometer for high temperature measurements has a sensor head comprised of a solid-state video camera operated in fixed gain mode, preferably one with a charge injection device detector, an infrared filter, and a lens system to image a radiating object on the detector array. Spectral response of the system is limited to 700 to 1100 nanometers or a smaller portion of this near-infrared band. The video signal output of the sensor is processed and object temperature is displayed on a television monitor; alternatively the video signal is presented to a digital frame grabber and converted to a temperature map.
