Paper Abstract

Three Methods of adaptation are briefly compared: (1) Periodical correction of a surface of a Primary Mirror of Millimeter Radio Telescopes as it planned, for example, for 100-m GBT (USA) and 70-m RT-70 (Russia-Uzbekistan), by means of measuring of positions of each Primary Segments with the help of the Laser Rangefinders for Trilateration Surface Retroreflectors. (2) Continuous correction of a surface of a Primary Mirror of a Millimeter Radio Telescope by method in which each of Primary Segments independently clings itself to maxima of fringes of two intersecting Optical Interference Fields, created over a surface of a Primary Mirror by an axial Laser (proposed by author, in 1993), (3) Correction of a wave- front in a real time by means of modified Adaptive Optics Technology, for example the 'Two-Stage Optics Concept' scheme, successfully used for optical Telescopes. Advantages and problems of application to a Millimeter Radio Telescope are briefly considered.
