摘　　要：提出一种用于空间激光通信综合参数测试的双通道望远系统，长焦通道满足端机远场分布等参数的测量，无焦望远通道可用于跟瞄性能测量。分析了空间激光通信端机远场分布及跟瞄性能测试的原理，设计了一套双通道望远系统装置，该装置光学系统可分别构成离轴卡塞格林系统或离轴三镜无焦望远系统，工作谱段为800—1700nm，通光孔径为300mm。完成了系统的研制和装调，并进行了性能检测，结果表明，长焦通道波像差为0．097h．（λ=632．8nm），无焦通道波像差为0．048λ，均满足设计指标要求。A design of a double channels telescope system for space laser communications synthetic parameter test is proposed. The long focal channel can be used for far field distribution measurement of the terminals and afocal channel can be used for the measurement of tracking and pointing accuracy. The principle of the measurement of the far field distribution, tracking and pointing accuracy of space laser communication is analyzed. A double channels telescope system was designed which could construct off-axis Cassegrain system or of-axis three-mirror afoeal system, respectively. The working spectral range of the system is 800 - 1 700 nm and the clear aperture size is 300mm. The performances of the system were tested. The test result demonstrates that the wavefront error of long focal channel is 0.097λ （λ = 632.8 nm）, and the wavefront error of afocal channel is 0.048λ which both meet the design requirements.
