FORMATION OF THE MAIN FEEDBACK IN THE AUTO-ALIGNING SYSTEM, BASED ON OPTICAL SWITCH FOR MULTICHANNEL LASER SYSTEMS
In this article presents an approach to the formation of the main feedback in auto-aligning system for multichannel laser systems equipped with an optical switch. Optical switch allows get quasicontinious mode of radiation on account of speed switching of laser modules in a single optical path. Also, optical switch has the function of laser radiation’s auto-aligning. This function is based on the radiation axis’s position error signal generated by main feedback. There was proposed the use of speed cameras to capture designated laser beams and subsequent mathematical analysis of the video recordings. In this article the laws for analyzing video frames and calculating the resulting misalignments of laser radiation. Mathematical operations have been based on laws of the geometric optics. Based on the research results there were selected elements of the auto-aligning system. Obtained mathematical laws were included into a computer program that produces the main feedback for optical switch’s manipulator.
