Abstract

Microprocessor radiometer with two-channel diaphragmatic optical system for high-precision measurements in infrared wave band (2–25 µm) is designed. The radiometer allows for measuring the surface temperature in 10–500°C range with maximum error not exceeding 0.5% and ensures viewing angle of 1:50. Certain results of using the radiometer in biomedical research are provided.
