英文摘要	Focal plane assembly of space remote sensor is a key component of space remote sensor, which is used to finish the transition function of the light signal into electrical signal. The focal plane assembly should have the characteristics of high splicing accuracy, high stability and high lightweight performance. In view of the function requirement of a deep space remote sensor with push-scan imaging and staring imaging, a focal plane assembly whose substrate was common with CCD detector and CMOS detector was designed, the focal plane assembly included focal plane substrate, CCD component, CMOS component, video processing circuit board, and so on. With a reasonable layout, the focal plane assembly was designed with three pieces of CCD and two pieces of CMOS, which was a compact structure and had a good heat dissipation effect. Moreover, the electromagnetic compatibility performance of focal plane assembly was improved obviously with the means of copper segment and box structure covering. After the assembling of focal plane assembly, the lapping error of CCD detector was better than 2 m, the collinearity and parallelism error of detector of CCD and CMOS was better than 2 m, the coplanarity error was better than 2.5 m. Finally, the force and thermal tests were carried out for the focal plane assembly, and the collinearity, parallelism and coplanarity errors of the detector did not change, indicating that the focal plane component has high enough splicage accuracy and stability. The fundamental frequency of the focal plane assembly is 135 Hz, which had sufficient dynamic stiffness. At the same time, the electromagnetic compatibility test was carried out on the space remote sensor, with good performance. 2020, Editorial Board of Journal of Infrared and Laser Engineering.
