DEVICE FOR AUTOMATIC ADJUSTMENT OF TWO-MIRROR TELESCOPIC SYSTEM WITH GIVEN DIRECTION OF OUTPUT RADIATION RELATIVE TO VIEWING DIRECTION Russian patent published in 2024 - IPC G01B11/27 G02B27/62 

FIELD: control and measuring equipment.

SUBSTANCE: invention relates to control and measuring equipment and is aimed at providing in the automatic adjustment mode the specified direction of the radiation output from the double-mirror telescopic system relative to the viewing direction. Device comprises a housing with inlet and outlet windows, a primary mirror (PM) and a secondary mirror (SM) with a diagonal mirror (DM) arranged between them with two tilt drives, first, second, third, fourth and fifth flat mirrors-imitators, where the first, third, fourth and fifth flat mirrors-simulators are rigidly connected to (PM), and the second is rigidly connected to (SM). Also contains two drives of inclination and three drives of linear displacements (SM); processing and control unit; first and second pentaprism, first and second photoelectric autocollimator (PEA), first rotary rhombus-prism with a drive, optically connected to the second (PEA), a second rotary rhombus-prism with a drive, optically connected to the second (PEA) through the first and second pentaprisms; a first periscope system, through which the first and second mirrors are optically coupled with first (PEA); second periscope system; first lens with a central axial hole, rigidly connected to (PM); second lens with a hole made along its optical axis, a luminous mark rigidly connected to (SM); night (first) sighting device and day (second) sighting device. Device includes a first light source with a light wavelength λ₁ and a second light source with a light wavelength λ₂; optical fibre, first and second collinear beam transfer devices (CBTD), each of which comprises a support pipe with end reflectors fixed at its ends, made in the form of pentaprisms; first prism BkR-180° optically connected to the first (CBTD) and the second prism BkR-180° optically connected to the second (CBTD); third rhombus-prism, installed between the second lens and the end reflector of first (CBTD); first optical wedge installed in the course of light beams from the first (CBTD) to the first sighting device; the second optical wedge is installed in the course of light beams from the second (CBTD) to the second sighting device.

EFFECT: providing automatic adjustment of the specified direction of the radiation output from the two-mirror telescopic system relative to the viewing direction.
