Experimental Determination Of The Parameters Affecting The Vander Lugt Filtering Procedure For Non-Destructive Testing Application

Relationship between correlation intensity and a bias exposure, a beam balance ratio ,and a spatial frequency band are determined experimentally. It is shown that a spatial frequency spectrum of wanted input signal, for which filter is opticaly matched, is affecting the synthesis procedure.© (1983) COPYRIGHT SPIE--The International Society for Optical Engineering.
