Laser scanner

摘要

A laser scanner includes an optical source emitting a laser beam; and an optical deflector deflecting the laser beam emitted from the optical source to scan an object with the laser beam deflected thereby, wherein the optical deflector includes a reflecting mirror; a motor rotating the reflecting mirror around an axis of the mirror: a first member fixed on a shaft of the motor, rotating with the shaft and a second member fixed on the axis of the mirror, engaging with the first member when the shaft rotates to rotate with the axis of the mirror.

主权项

1. A laser scanner, comprising:
an optical source configured to emit a laser beam; and an optical deflector configured to deflect the laser beam emitted from the optical source to sea an object with the laser beam deflected thereby, wherein the optical deflector comprises:
a reflecting mirror;a shaft;a motor configured to rotate the shaft fixed to a motor axis of the motor;a first member fixed on the shaft and configured to rotate with the shaft;a mirror axis having an end thereof coupled to the reflecting mirror; anda second member fixed on another end of the mirror axis and configured to engage with the first member when the shaft rotates, to cause the second member and the mirror axis to rotate along with the first member when the motor drives the shaft to rotate, and wherein the shaft and the mirror axis are distinct from each other, and even when the shaft rotates with eccentricity, the reflecting mirror rotates without eccentricity.
