摘要
讨论了几种用于克服斩波调制模式红外电视温度标定困难的技术，包括用乘法器补偿响应率的非均匀性；用数字式像差处理器消除本底电流的非均匀性；用多场平均技术提高信噪比等．介绍了使用红外电视测量目标温度的方法．
Several techniques, such as the compensation for the nonuniformity of the responsivity with a multiplier, the elimination of the nonuniformity of the background current with a digital type alteration processor, the improvement of the S/N ratio with multiple field averaging technique, to overcome the difficulties met in the temperature calibration of infrared TV systems are discussed. Several methods used to measure the object temperature with infrared TV are described.
