COSMIC TELESCOPE (VERSIONS) Russian patent published in 1997 - IPC

FIELD: instrumentation for astronomy, design of cosmic telescopes with controlled form of surface of main mirror or correction of wave front by special compensators with use of devices controlling wave front of telescope. SUBSTANCE: in agreement with first version essence of invention lies in that telescope has main 5 and secondary 6 mirrors, guidance and hydrogenation system, receiving system and system controlling form of surface of main mirror 5 incorporating point radiation source 1, interferometer 8, additional convex or concave mirror 4 put between curvature center of main mirror 5 and secondary mirror 6 and facing main mirror 5 with reflecting surface. Point radiation 1 is positioned in plane optically coupled to plane passing through curvature center of main mirror 5. Cosmic telescope manufactured in accordance with the second version differs from design of telescope described above by form of additional mirror 4a; it is made flat and by lens corrector 3 mounted between additional mirror 4a and interferometer 1. EFFECT: simplified design and improved operational characteristics. 4 cl, 3 dwg
