Abstract

In the laser communication terminal in space

the scanning trajectory on the CMOS camera is not orthogonal when the fine pointing mechanism of the 45° scanning mirror vibrates around different shaft systems

which reduces the scanning probability and makes it more difficult to calibrate the optical axis of the laser terminal in orbit. In order to solve this problem

the ray tracing method is used to establish a three-dimensional light vector scanning trajectory model

and the orthogonality of the light vector trajectory on the CMOS camera is calculated and simulated when the vibration axis of the 45° mirror scans along two sets of commonly used orthogonal axes. Then

an experimental test system is built to verify the performance of the reflected light vector in the scanning process of the fine pointing mechanism. The results show that: the non-orthogonality of the 45° scanning mirror vibrates around

is 19.47°

and the included angle of the scanning trajectory on the CMOS camera changes with the scanning angle according to the relationship between the scanning angle and the orthogonality curve of the sc

anning trajectory; the non-orthogonality of the scanning trajectory is 6.4 mrad when the scanning angle is 9 mrad. This study provides insights into the internal mechanism and has guiding significance for the installation mode and optical axis calibration of the off-axis field of view of the fine pointing mechanism of space laser communication terminal.

For improving the angular accuracy of a scanning mirror based on the eddy current displacement sensor measurement, an angular error-correction method is proposed and demonstrated. A mathematic angular error model with physical parameters was developed, and the cross-validation method was employed to determine the reasonable order of the Maclaurin series used in the error model, which increased the exactitude and robustness of the correction method. The error parameters were identified by accurately fitting the calibrated angular errors with the error model, which showed excellent error prediction performance. Based on the angular calculation model corrected by the error model, the closed-loop control system was established to obtain accurate deflection angles. Experimental results show that within the deflection angle of ±1.5 deg, the angular accuracy was improved from 0.28 deg to less than 1.1 arcsec, and the standard deviation for six measurements was less than 1.2 arcsec, which indicates that the angle correction method was effective in improving the linearity of the eddy current sensors and reducing the influence of manufacturing and installation errors.
