Abstract
Visibility of interference fringes, as known, is defined by the ratio of intensities of measuring and reference waves. In interferometric measurements, intensity of measuring wave depends on reflection coefficient of an object under test. The difference between the intensities of reference and measuring waves causes visibility decrease of interference fringes. In the present paper, a possibility of controlling the fringe visibility by introducing two reference waves with mutual phase shift between them is considered for the cases of monochromatic and broadband light sources.
