摘要

Abstract: An automatic interferometric method is proposed for measuring the transmission peak wavelength of monochromatic filters and their bandwidths. The fringe interference field is sampled by a standard CCD camera and processed using a PC computer. These above mentioned spectrometric parameters of filters follow from the analysis of the interfringe spacing and fringe intensity distribution (visibility of fringes). A known double-refracting interference microscope was used in the performed experiment.!4
