In this paper, we analyze in detail the features of the application of the magneto-optical imaging technique for studying HTS tapes. We present a detailed description of the experimental technique and features of the research facility for low temperatures research. The features of the penetration of a magnetic field into a superconductor are described, and the procedure for calibrating a magneto-optical film and algorithms for calculating magnetic field profiles from magneto-optical images are described in detail.
