Abstract

This paper introduces an automatic system for maintaining the zero interference band in interferometric measurements. It facilitates precise measurements of maximum (Imax) and minimum (Imin) intensities across the investigated area for interference pattern visibility. The system employs a piezoceramic modulator for interference fringe generation, synchronized detectors for simultaneous Imax and Imin registration, and automatic phase control to ensure phase coherency. This system enhances measurement accuracy and efficiency, finding applications in interferometric experiments involving phase-inhomogeneous objects and dispersive media.
