摘要:
测量星敏感器成像面与安装面的位姿关系,对系统成像质量及精度补偿具有重要意义.本文设计了一套基于三维导轨的探测器成像面姿态检测设备,针对检测设备的系统误差提出了一种误差快速补偿方法,通过对标准件的测量完成对导轨运动误差在Z方向分量的标定.将X轴和Y轴运动体的位移量与测量误差在Z方向的分量数据写入标定文件,以高效完成误差的补偿.通过与高精度激光干涉仪测量结果对比,Y轴测量误差在2.9 μm内,X轴测量误差在1.5 μm内,达到了测量要求.
Abstract:
The attitude detection between the imaging plane of the star sensor and the installation plane is of great significance to the system image quality and accuracy compensation. A set of imaging plane attitude detector based on the three-dimensional rail is designed, and a fast error compensation method is proposed to compensate the system error of the detector, which can calibrate the rail motion error in the Z direction by measuring the standard parts. The displacements of the X axis and Y axis moving bodies and the measurement error in the Z direction component data are written into the calibration file to complete the error compensation efficiently. Compared with the measurement results of high precision laser interferometer, the measurement error of Y axis is 2.9 μm and that of X axis is 1.5 μm, which meets the requirements of measurement.
