In this article, we investigate the physical and mathematical model of a coherent optical spectrum analyzer (COSA), which uses a matrix light modulator and a matrix detector as input and output devices. This model allows to define distortions in the

We used the mirrorshadow method for the diagnostics of stressedstrained state of shaped sections of metal structures. It was found that in the course of implementation of this method there may occur an error that is caused by misalignment of meas
