In other embodiments, the optical element 42 may also be mounted on the optical component 22.

[0039] In addition to being directly mounted in the receiving slot 232, the optical element 42 can also be indirectly or directly fixed to the optical device 23 via a mounting bracket. The mounting bracket can be fixedly connected to the optical device 23, the base 1, or the optical element 22.

[0040] like Figure 3 As shown, the driving assembly 5 drives the optical device 23 and / or the optical element 42 to rotate. The driving assembly 5 drives the optical device 23 to rotate, and the optical device 23 and the optical element 42 rotate at the same speed; or the optical device 23 and the optical element 42 rotate at different speeds; or the optical device 23 rotates while the optical element 42 remains stationary. When the optical element 42 is stationary, the rotational speed of the optical element 22 is different from the rotational speed of the optical device 23, or the rotational speed of the optical element 22 is opposite to the direction of movement of the optical device 23. Alternatively, it can be said that the rotational speed of the optical element 22 is different from the rotational speed of the optical element 42, or the rotational speed of the optical element 22 is opposite to the direction of movement of the optical element 42.
