针对摆扫面阵成像设备对地摆扫成像过程中产生的图像像移,研制了一种悬臂式高频像移补偿装置,通过补偿镜高频振动以补偿扫描像移。基于摆角音圈电机控制及结构简单的优点,采用摆角音圈电机作为驱动,进行了高频像移补偿装置设计及结构有限元仿真分析。高频像移补偿装置外形尺寸为87mm(长)×81mm(宽)×172mm(高),质量约1kg,实际光学补偿口径为53mm。设计了机载对地摆扫成像验证系统进行高频像移补偿成像验证。通过对地成像飞行实验验证了高频振动像移补偿性能,成像像质清晰,当高频像移补偿装置的补偿角度为1°时,振动补偿频率可以达到50Hz,补偿精度优于0.2%。通过像移补偿装置研制及对地成像系统设计验证为面阵探测器大视场对地成像系统提供了技术参考。
According to the image motion generated in the process of ground scanning imaging by swing scanning array imaging equipment
a cantilever high-frequency image motion compensation device has been designed. The high frequency vibration of the compensating mirror is used to compensate the image motion. Based on the advantages of simple control and structure
the high frequency image motion compensation device is designed by using the swing angle voice coil motor as the drive,and the finite element simulation analysis of the structure is carried out. The size of the high-frequency image motion compensation device is 87mm (length) × 81mm (width) × 172mm (height)
the mass is about 1kg
and the actual optical compensation aperture is 53mm. The airborne swing scanning verification system of ground imaging is designed for high-frequency image motion compensation imaging verification. The performance of high-frequency vibration image motion compensation is verified by ground imaging flight experiment
and the image quality is clear. When the compensation angle of the high-frequency image motion compensation device is 1°
the vibration compensation frequency can reach 50Hz
and the compensation accuracy is better than 0.2%. The development of the image motion compensation device and the design verification of the ground imaging system provide a technical reference for the large field of view ground imaging system of the array detector.
