Abstract
Possible variants of the sensor equipment based on the pseudo-circulation of the wave front of the measuring beam and photoelectronic-optics amplification of the angular misalignment signal are considered. Evaluation of the characteristics of these sensors allows us to conclude a possibility of creating measuring systems that meet the requirements of the “Millimetron” telescope.
