摘　　要：红外可以获得可见光难以获取的目标景物信息,红外辐射特性作为一种重要的光学表征方式,目前广泛应用于目标的跟踪和识别。某光电经纬仪具备中波红外跟踪功能,针对目标红外特性探测的需求,需要对其红外系统继续设计改造。本文结合设备实际情况,分析了红外辐射特性测量系统的组成及工作方式,从红外辐射温度漂移补偿、红外辐射标定方程获取、相机动态范围计算几个方面对该光电经纬仪进行改造设计,通过试验对改造后的指标进行测试验证,结果表明设计方案合理,能够达到预期目标。IR can obtain the object information that is difficult to be obtained by the visible light. The infrared radiation characteristic is an important optical characterization,and it is widely used in target tracking and identification. A certain theodolite can be used as middle infrared target tracking device. According to the detection requirement of target infrared radiation characteristics,the infrared system of the theodolite needs to be modified. The composition and working theory of infrared radiation measurement system are analyzed. The infrared system of the theodolite is designed from several aspects including the temperature drift compensation,calibration equation acquisition and the dynamic range calculation of the camera,and the performances of the new system was tested. The results show that the design is reasonable,and can reach the expected goals.
