Background
In a laser or laser processing system, the optical path is often deflected, and two mirrors are usually used for control. As shown in fig. 1, M1 and M2 are mirrors, and the distance between the outgoing ray and the incoming ray can be controlled by changing the distance between M1 and M2, and this method is inconvenient for use because the outgoing ray needs to be accurately adjusted to be parallel to the original ray after the mirrors are added.
In addition, if the deflection distance is required to be very small, this requires the two mirrors to be very close together, but the mirrors are of a certain size and thickness and therefore cannot be infinitely close together, which makes it difficult to achieve when the deflection distance is required to be very close.

Therefore, it is desirable to develop a new adjusting device for optical path/light deflection to solve the above problems.
