Abstract

The IR scene simulation technique is an effective method to test the responsivity, the precision and the anti-interference capability of the IR detector during its research and development; thus the technique may reduce the cost and research time. Currently, the IR scene simulation technique based on MOS-Resistance arrays is one of the most popular IR scene simulation techniques. However, resistance arrays can only be heated, but not refrigerated. Moreover, other simulation techniques also have the problem of one-direction IR scene simulation. In this paper, the IR simulation mechanism is studied in detail. According to the analysis of the characteristic of the semiconductor device based on the Peltier effect , the bidirectional IR scene simulation technique based on semiconductor refrigeration device with the Peltier effect and the computer controlling technology is put forward. Moreover, a prototype machine is designed ,and the shortcoming of the IR scene simulation system based on MOS-Resistance arrays which can only be heated is avoided. Finally, the performance of the prototype machine is tested by experiments. The results show that the system can realize bidirectional IR scene simulation perfectly by the means of increasing and reducing the temperature.
