Abstract

The present disclosure is directed to a device having an optical scanner, the optical scanner structured to include a mirror, a first actuator that rotates the mirror around a first axis of rotation, a first angular position sensor that senses an angular position of the mirror around the first axis of rotation, a second actuator that rotates the mirror around a second axis of rotation, a second angular position sensor that senses the angular position of the mirror around the second axis of rotation, and a controller coupled to the first and second drivers and structured to drive the respective first and second actuators to rotate the mirror into respective specific angles around the axes of rotation as sensed by the respective first and second angular position sensors.

Description

technical field [0001] The present disclosure relates to a compact optical scanner with a single moving mirror arranged to deflect an electromagnetic beam to a desired direction in space with high precision given by spherical coordinates (azimuth, inclination). Background technique [0002] In general, known scanners for scanning a beam of light on a two-dimensional surface comprise two mirrors mounted to rotate about mutually perpendicular axes of rotation so that one mirror scans the beam along the x-axis on the surface and the other along Scan the beam along the y-axis on the surface. [0003] Scanners with a single moving mirror are also known, where the mirror is arranged to rotate about two axes of rotation. The accuracy and range of angular deflection of such scanners is still lower than that of scanners with two mirrors. Contents of the invention [0004] According to one embodiment of the present disclosure, the optical scanner is provided with mirrors mounted t...
