摘要：Knowing the dark current correction parameters is fundamental to carry out radiometric calibration of a digital camera. To obtain these parameters it is necessary to keep the CCD device temperature constant, since the dark current is resultant from the thermal agitation and its generation rate is strongly correlated with the device temperature. In this paper it is proposed the use of a thermoelectric cooling device for decreasing and controlling the system temperature and a thermistor sensor to measure and monitor the temperature of the system. The proposed cooling system was coupled into a Magi DC575 camera and the obtained results have been presented in graphs and pictures. Results have confirmed both its applicability and potentiality in the refrigeration process and stabilization of the temperature of the digital camera.
