TELEORIENTATION TEMPERATURE-COMPENSATING LASER SYSTEM Russian patent published in 2004 - IPC

FIELD: instrumentation engineering; generation of information field for teleorientation and navigation laser systems, optical communications.

SUBSTANCE: proposed teleorienting laser system that can be used to control movable objects such as controlled rockets, for controlling, landing, and docking flying vehicles, piloting ships through narrow waters or bridge vaults, and the like has laser 1 incorporating radiator 2 and collimator 3, X-Y acoustooptical deflector 4 incorporating two crossed anisotropic acoustooptical cells 5, 6, all mounted in tandem, as well as polarized prism 8, third acoustooptical cell 7 mounted in the same way as second one, first telescope 10, second telescope 11, optical reflector 9 inserted between second output of polarized prism and second telescope, series-connected sync pulse and raster parameter shaping unit 12 and raster code shaper 13, and also dual-cannel high-frequency signal switching unit 16 and dual-channel frequency synthesizer 15 whose first output is connected to first acoustooptical cell, second output, to high-frequency input of dual-channel high-frequency signal switching unit, outputs of the latter being connected to second and third acoustooptical cells and control input, to range switching output of sync signal and raster parameter shaping unit; newly introduced in teleorientation laser system are alignment unit 17, multiplexer 18, temperature-compensation unit 20, and two adders 14 and 19; alignment enabling and data setting inputs of alignment unit are connected to peripheral mode-selection and data-setting devices; two data outputs of alignment unit are connected to inputs of multiplexer whose output is connected to first input of first adder; data output of temperature-compensating unit is connected to second input of first adder whose output is connected to second input of second adder; first input of second adder is connected to outputs of raster code shaper and outputs, to inputs of frequency synthesizer; range switching output of sync pulse and raster parameter shaping unit is connected to multiplexer control input.

EFFECT: enlarged operating temperature range, reduced error in guide control due to external control in process adjustment and in elimination of system maladjustment.
