Software and hardware implementation of the algorithm for 2-mirrors automatic laser beam alignment system

Abstract

The semi-automatic system for laser beam alignment was developed and researched. The alignment system was used to make the laser beam follow the predetermined path through the optical scheme (basically a series of reflective surfaces such as mirrors or lenses). The algorithm and the software to control the system was developed and tested. The system contained of diode laser source, two gimbal mirror mounts with stepper motors, multi-axis motion controller, near field sensor, far field sensor, wavefront sensor, and control software. It allowed to control the positioning of the beam, tip-tilt and overall curvature of the wavefront.
