The method of removing the cooling circuit to reduce the power consumption and the volume in the infrared imaging system has become the mainstream of the configuration of the infrared thermal imager,but in the case of no refrigeration circuit,the infrared imaging effect will be affected by the ambient temperature and self-heating.A correction method of temperature compensation is designed.The method adopts the processing scheme of first calibration and then compensation.Based on the hardware platform,the output image of infrared detector is realized without TEC cooling circuit under the temperature compensation correction.The experimental results show that the proposed method can effectively suppress the interference of infrared temperature fluctuation on infrared imaging effect without the cooling circuit.
