AI Technical Summary
Existing Richcomb detection methods for detecting surface shape errors in large-aperture plane mirrors rely on high-precision measurement of system length or consistency of plane mirror position for the removal of system power errors. This results in limitations in hardware conditions and measurement accuracy, leading to insufficient detection accuracy and information loss.
A two-angle Power iterative fitting method is adopted. By obtaining the wavefront of the Richter-Common two-angle interferometric detection, the optimal Power coefficient is automatically calculated iteratively, which simplifies the detection process, reduces the dependence on the accurate measurement of the system length value, and removes the Power error by fitting and solving the problem using the least squares method.
It achieves efficient separation of system defocus error even when the amount of defocus error is unknown, improves the accuracy and detection efficiency of planar mirror shape restoration, preserves intermediate frequency information, and simplifies the detection operation.
