A method of increasing the correction capability of the deformable mirror method

When the present invention discloses a method for improving the deformable mirror correction capability, the number of drives in the deformable mirror used is constant, the deformable mirror while using a first driver and a second driver for changing the reflectivity of the deformable mirror surface shape for the former incident on said laser beam wave reflection surface of the deformable mirror distortion correction, was the first driver and a second driver alternately arranged is provided on a surface of the deformable mirror, and said first drive scope R1 of the deformable mirror is greater than the second scope drive of the deformable mirror R2. The present invention has a different scope of two drive by using, as compared to a single scope of the drive design, in the same mirror driver density modification, improved correction of the frequency of the deformable mirror, to improve the deformable mirror light wave laser correction capability before, you can get a better laser focal spot.
