摘要
对比分析现有光束扫描系统的优劣,提出采用二维振镜扫描系统作为多光谱集成靶标的光轴调向装置,光轴调向装置的调向精度影响多光谱集成靶标的校准精度。通过对二维振镜扫描系统调向误差进行分析,建立二维振镜扫描系统调向模型,并进行了二维振镜扫描系统调向误差测量实验。结果表明:二维振镜扫描系统的方位角误差和俯仰角误差小于8″,调向角误差小于9″,调向误差小于10″,能够满足多光谱集成靶标光轴调向精度要求。
The advantages and disadvantages of existing beam scanning system were compared and analyzed.A 2 Dgalvanometer scanning system was used as the optical axis alignment device of the multispectral integrated target.The alignment precision of the optical axis alignment device can affect the calibration accuracy of the multispectral integrated target.The directional error of 2 Dgalvanometer scanning system was analyzed,the directional model of 2 Dgalvanometer scanning system was established,and the measurement experiment of alignment error of 2 Dgalvanometer scanning system was carried out.The results show that the azimuth error and pitch angle error of the 2 Dgalvanometer scanning system are less than 8″,the alignment angle error is less than 9″,and the alignment error is less than 10″,which demonstrates that the optical axis alignment accuracy of multispectral integrated target can be satisfied.
