DEVICE FOR AUTOMATIC ALIGNMENT OF TWO-MIRROR TELESCOPE SYSTEM TO GIVEN DIRECTION OF OUTPUT RADIATION Russian patent published in 2017 - IPC G01B11/27 G02B27/62 

FIELD: physics.

SUBSTANCE: device includes a main mirror (MM) 4, a secondary mirror (SM) 5, the first flat mirror-simulator 6 of the optical MM axis 4, rigidly connected with the MM 4 and perpendicular to the optical MM axis 4, and the second flat mirror-simulator 7 of the optical SM axis 5 rigidly connected with the SM 5 and perpendicular to its optical axis; the first photoelectric autocollimator (ACF) 8; the first periscope system 9; two slope drives 10, 11 and three linear displacement drives 12, 13, 14, SM 5 ; the first 16 and the second 17 pentaprisms. The first 6 and second 7 mirror-simulators are optically connected to the first ACF 8. The device includes a lens with the central axial hole 18, rigidly connected to the MM 4, a luminous mark 19, rigidly connected with the SM 5 located on its optical axis near its top and in the focal lens plane 18; the third flat mirror-simulator 20 of the optical MM axis 4, rigidly connected to the MM 4 and perpendicular to the optical axis; the second ACF 21, the first and the second rotary diamond prisms 22 and 24 with actuators 23 and 25 optically connected with the second ACF 21, a diagonal mirror 26 with two tilt actuators 27 and 28, between the MM 4 and the SM 5 .

EFFECT: safety in the automatic alignment of the two-mirror telescope system and the parallel of the primary mirror optical axis rays emerged from the system.
