A pure adaptive interferometer is proposed for optical free form surfaces metrology without
auxiliary devices such as the wavefont sensors and deflectometry systems for DM …

Since the testing of convex mirrors often requires a compensator with a larger aperture than
the mirror under test, this is undoubtedly a trade-off not worth pursuing. Moreover, for …

Instead of various mathematical stitching algorithms, an aspheric subaperture stitching
interferometric method relying on modern computer modeling technique is presented. Based …

A non-null annular subaperture stitching interferometry (NASSI), combining the subaperture
stitching ideal and non-null test method, is proposed for steep aspheric testing. Compared …
