Abstract

Coherent effects in the formation of interference images in microscope in quasi-monochromatic or frequency-broadband light (white light) with a wide angular spectrum (wide angular aperture) are considered. The instantaneous interference images with an instantaneous speckle structure were simulated on a computer and the effect of the width of the angular and frequency spectra of the optical wave field on the contrast of the interference fringes observed in the experiment was investigated.
