Spatial as well as temporal phase shift methods can be used. Optical testing, where computer analysis of interference fringes is becoming increasing important, will be discussed in connection with testing optical components, microprofiles as well as for testing aspheric surfaces. In addition, methods using heterodyne techniques and real time holography will be described.eninfo:eu-repo/semantics/openAccessHolographische Interferometrie , Optische Messtechnik530conferenceObject2014-11-03
