Abstract:
Temperature profiles of objects having large areas are measured and displayed by providing a plurality of radiometric sensors, each sensor having an established field of view and being directed toward the object whose temperature is being measured. Outputs of the sensors are processed to provide maximum sensitivity within a specified temperature range and little or no sensitivity outside of the specified range. Within a specified temperature range the temperature scale is divided into a number of increments, the number of said increments dependent on the desired degree of resolution of measurement. The processed and expanded output of each of the radiometric sensors is electronically compared and categorized into the selected divisions of the specified temperature range. Electrical signals derived from this comparison are provided to columnar displays associated with each radiometric sensor whereby the range of temperature is displayed and the output of each radiometric sensor is indicated. Location of the various elements of the display adjacently provides an indication of the profile of the temperature of the object being measured.
