Total internal reflection (tir) scanning device

Abstract

An apparatus includes an optical scanner including a reflective surface and a rear surface, where the optical scanner is mounted to rotate about a scanner. The apparatus includes a control system operatively coupled to the optical scanner. The apparatus includes a motor, operatively coupled to the control system, mounted in proximity to the optical scanner and having a shaft coupled to the optical scanner. The shaft rotates about a shaft axis parallel to the scanner axis causing the optical scanner to rotate about the scanner axis responsively to rotation of the shaft. The motor rotates the optical scanner to each of a set of positions at a respective time based on instructions from the control system. The apparatus includes an optical beam source, operatively coupled to the control system, positioned behind the optical scanner and configured to transmit an optical beam toward the optical scanner while the motor rotates.
