The first reflective surface and at least part of the second reflective surface are disposed at mutually different angles. When a first optical axis passing through the target object and the first reflective surface is parallel with a second optical axis passing through the target object and the second reflective surface, a third optical axis passing through the first reflective surface and the light source and a fourth optical axis passing through the second reflective surface and the photodetector are at a predetermined angle relative to one another.

摘要： A laser scanning module employs a scan mirror and magnet rotor subassembly supported by a stationary stator structure. The scan mirror and magnet rotor subassembly includes: a silicone frame having a pair of silicone torsional hinges (i.e. posts) aligned along a scan axis and a supported by a pair of support elements associated with the stator structure, to support the scan mirror and magnet rotor subassembly. When the scan mirror and magnet rotor subassembly is rotated about its scan axis, by forces generated by an electromagnetic coil structure acting on the permanent magnet mounted on silicone frame, the silicone torsional hinges are elastically distorted and generate linear restoring forces which return the rotor subassembly back to its home position about the scan axis.

摘要： The present invention is a sweeping or reciprocating laser scanning device. The reciprocation or sweeping motion is cam driven. As the cam rotates, a lever arm is reciprocated or oscillated between two positions, which causes the laser or beam of light to move linearly, thus creating a triangular plane of light resulting in a reciprocating linear reference across the hypotenuse of the triangular plane of light.
