Embodiment 1
[0053] see Figure 11 , this embodiment is a set of dual prism coarse-fine coupling scanning device, which is used to realize coarse-fine coupling scanning of laser beams in a wide range. Such as Figure 11 As shown, this embodiment mainly includes a base 33 , a laser bracket 34 , a laser 35 , a first prism assembly 36 and a second prism assembly 37 . Wherein, the first prism assembly 36 and the second prism assembly 37 are exactly the same, and both are single wedge prism coarse-fine coupling scanning devices described in the present invention. The first prism assembly 36 and the second prism assembly 37 are installed on the base 33 , the laser bracket 34 is installed on the base 33 , and the laser 35 is installed on the top of the laser bracket 34 . In this embodiment, the central axis of the laser 35 , the optical axis of the first prism assembly 36 and the optical axis of the second prism assembly 37 are on the same straight line. In this embodiment, both the first pris...
