Design and Implementation of Optical Axis Parallelism Detection System for Laser Ranging Direct-sight Mirror

The laser range finder integrates the functions of observation, aiming, display and ranging, etc. It is widely used in weapons and equipment. The parallelism between the laser transmitting axis, receiving axis and aiming optical axis directly affects the accuracy and hit rate of the weapon system. This paper introduces a set of quantitative triaxial parallelism detection system, which improves the detection accuracy of triaxial parallelism of laser range finder, and plays an important role in improving the aiming accuracy of weapons and equipment, respectively.
