APPLICATION OF ADAPTIVE FILTERS TO PROCESSING OF YOUNGS FRINGES

Some results obtained by the application of adaptive optical filtering to Young's fringe processing are presented. Light-developing layers f rom silver bromide (AgBr) are used in a filter block with a lens optic al configuration. As a result of the processing, suppression of the ze ro order in the fringe Fourier spectrum is obtained which changes the power distribution in the spectral orders and improves the information capacity of the spectrum. The spatial-frequency spectrum adaptively p rocessed is analysed with the aid of a numerical algorithm to determin e the fringe informative parameters, i.e. fringe spacing and orientati on.
