PRECISION LASER BEAM POSITIONING SYSTEM INSTALLATION TESTING STRUCTURES OF BIOLOGICAL MATERIALS

Abstract

A system for automatic control of the angular position of the laser beam to set the test structures of biological ma-terials with the drive motion from the piezoelectric motor is developed. Stepper motor operation is ensured by imple-menting the algorithm of the program driver control using digital signal controller and communication protocol be-tween the computer and the controller.
