An optical sensor for measuring small displacements and rotation angles is described. Based on a non-contact principle of operation, which can be used to control small movements in installations to determine internal friction by the type of torsion pendulum. The main characteristics of the device are shown and the installation and connection diagram is shown by means of the ADC to the computer
