传统红外辐射探测装置的调理电路由场效应管和高阻抗运放组成，探测灵敏度较低、输出不稳定且场效应管极易损坏，对红外辐射探测装置的可靠性带来负面影响，从而影响到弹药、武器系统的正常测试。本文采用运算放大器作为调理电路，使用带有瞄准具的小视场光学系统并整体设计红外辐射探测装置。采用差分信号输出，提高长距离传输脉冲信号能力，方便后续处理及直观观察，同时也有效提高了探测装置的灵敏度，抗干扰能力强、轻巧、适用于各种环境。
傳統紅外輻射探測裝置的調理電路由場效應管和高阻抗運放組成，探測靈敏度較低、輸齣不穩定且場效應管極易損壞，對紅外輻射探測裝置的可靠性帶來負麵影響，從而影響到彈藥、武器繫統的正常測試。本文採用運算放大器作為調理電路，使用帶有瞄準具的小視場光學繫統併整體設計紅外輻射探測裝置。採用差分信號輸齣，提高長距離傳輸脈遲信號能力，方便後續處理及直觀觀察，同時也有效提高瞭探測裝置的靈敏度，抗榦擾能力彊、輕巧、適用于各種環境。

The regulating circuit of traditional infrared radiation detection device is composed of field effect tube and high impedance op-amp.It has low detection sensitivity,low output instability and the field effect tube is easy to be damaged.That makes a negative impact on the reliability of infrared radiation detection devices,thus affecting the nor-mal test of ammunition and weapon systems.In our design,the operational amplifier was used as a regulating circuit, and small field of view was adopted.Differential signal output can improve the transmission capability of pulse signal at a long-distance,and make it easy to the following treatment and intuitive observation.That effectively improves the sensitivity of the detection device.The system has strong anti-interference ability and good adaptability.
