| 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. |
