Abstract

This study considers the specific aspects of controlling the surfaces of optical glass-ceramic-based components of assemblies with solder connections. The relief analysis is based on phase-shifting interferometry with selection of the operation laser wavelength corresponding to the intrinsic absorption band of the studied samples to eliminate the negative effect of interplane interference and local metallization. We demonstrate the possibility of successful application of the proposed approach to both quality control of mass-produced elements of laser gyroscope sensors and research on optimal technological solutions for assembling the constructions consisting of Astrositall or its analogs.
