摘　　要：针对红外系统检测设备的小型便携化需求,分析了检测仪的基本组成及对其进行小型设计的重点部位,分别从优化设计指标、采用离轴抛物面多次反射光路设计、选用硬铝作为镜片加工材质等方面对红外平行光管进行了优化设计,有效减小了光路系统的体积,减轻了平行光管的重量。采用紫铜辐射面、热电制冷器、散热片等构造了小型高效的黑体辐射源结构,设计了温度控制驱动电路,实现了小型轻量的面源黑体。所研制的检测仪整机重量小于15 kg,实现了小型便携,并取得了理想的应用效果。In light of the miniaturization and portability demand for test equipment of infrared system,the basic composition of test equipment was analyzed,as well as the key parts for miniature design.The design of infrared collimator was optimized by optimizing the design parameters,adopting the optical path design of off-axis parabolic multiple reflections,and selecting duralumin as the machining material of lens,which effectively reduces the volume of optical path system as well as the weight of infrared collimator.A small high-effective black-body radiation source structure was constructed by using red copper radiant surface,thermoelectric refrigerator,cooling fins,etc.,and a temperature-controlled driving circuit was designed,realizing the small lightweight surface source black-body.Overall weight of the test equipment developed is less than 15 kg,which realizies the goal of miniaturization and portability with desired application effect.
