Abstract

The influence of an angular spectrum of light fields (formed by extended light sources or at sharp focusing using high numerical apertures) on the signal of a low-coherence interferometer is discussed. The reduction of amplitude of the interferometer signal at probing of layered object owing to a broad angular spectrum has been shown both experimentally and by computer modeling.
