The invention discloses a wave plate design and error correction method in a contrast ratio adjustable point diffraction interference system. The light beam polarization state is adjusted in the modeof placing a quarter wave plate in a detection path, and then the interference stripe contrast ratio is adjustable. The problem is solved that when the wave plate is placed in a divergence spherical wave, a large wavefront error is generated. The wave plate design and error correction method is characterized in that that a flat and convex glass substrate of which the convex face is a non-sphericalface is adopted for the wave plate, and a plane is plated with a polarization membrane layer. Through even-order non-spherical design of the wave plate substrate, a wavefront distortion aberration caused when a large numerical value aperture sphere is detected is greatly lowered.

Since the even-order non-spherical quarter wave plate is fixed in design position in the detection path, after the pose error is corrected, the position of the wave plate does not need to be adjusted according to the change of the aperture numerical value of a mirror to be detected. The point diffraction system is easy to adjust, and the detection efficiency is improved.
