Fringe pattern discriminator for grazing incidence interferometer

摘要

permeability and thickness of the plane parallel to the flat also change the information relating to the tests reputation includes two types of information which it is obtained from the strain to determine the nested grazing incidence interferometer interferogram. The grazing angle of an interferometer is varied, within the nested interferogram only the modulation frequency of the local intensity stripes are determined. The local strength stripes characterized by the other interference patterns is determined by the respective modulation frequency.
