Laser and holographical testing possibilities for segments location and alignment processes of hyper high-aperture and extremely light optical telescope multiple mirrors

摘要

Based on the use of axial computer-generated holograms system and coherent behavior of laser radiation sources, it is proposed to control location and alignment processes of segments of the multiple mirrors used in hyper high-aperture and superlarge optical telescopes. The possibilities of identifying the inaccuracy sign and magnitude from the given position of each of the 24 identical panels from one out of four tiers, as well as the inaccuracy sign and magnitude of neighboring tier panels interposition at the places of their "coupling/attaching" were considered, based on the example of solving a problem of controlling the location and alignment processes of the carbon panels of the multiple primary mirror in "Millimetron" space observatory.
