Abstract

Optical axis consistency is an important index of multi-axes equipment. Most test methods of optical axis consistency are aimed at the consistency of multi sighting axes, or consistency between sighting axis and laser emission axis. It is difficult for consistency test between sighting axis and laser detection axis. A new method based on field testing was put forward to solve the difficulty of consistency check between sighting axis and laser detection axis. At first, sighting axis was set down as base, and high precision numerical turntable was used to adjust laser detection heading, and then the total field of view of laser detection channel was measured. The laser detection axis was gotten subsequently. Finally, the consistency error of sighting axis and laser detection axis was worked out, by comparing sighting axis’s angular position with the angular position of laser detection axis. There are many merits of the method, such as high precision, wide applicability, and easy to operate, etc. Meanwhile, the field of view of laser detection channel was checked out. This paper showed that the method we put forward can meet the demand of consistency check between sighting axis and laser detection axis well.
