    The high accuracy radiometric calibration method and technology is one of the primary technologies of modern remote sensing. Spectral radiance standard detector is a key unit of the new high-accuracy radiometric caliSration technology, and has potential applications in radiometric calibration of field, air-borne and space-borne sensors. The temperature change of spectral radiance standard det.ector is a primary factor of affecting its precision and stability. In order to keep the high accuracy of standard detector, a high-accuracy temperature-controlling device is needed to develop. We introduced a new digital thermometer DS18B20 in detail and designed a high-accuracy temperature controlling devices based on DS18B20. The experiment results prove that the temperature-controlling devices we designed can effectively decrease the temperature coefficient of spectral radiance standard detector and is reliable.
