Digitalisation Processing Technique for Interference Pattern with Obstruct
The principle and method of digitalisation processing technique for interference pattern with obstruct are introduced. The method of dividing region by threshold value and Sequence tracking edge points using the characteristic of phase-shift interferometry are discussed. These techniques have been successfully applied to measure the surface and wave aberration of the system with obstruct.
