METHOD FOR LASER TELEORIENTATSII OBJECT AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: physics.;SUBSTANCE: motion path of a controlled object is changed through angular adjustment of the control field of the object, which is carried out successively using two rectangular laser rasters turned about each other by 90° and formed by scanning a laser beam in each raster in one continuous line. The continuous line is formed using two crossed anisotropic acousto-optical cells to which high-frequency chirp signals, the frequency range of which is defined by angular dimensions of the laser rasters, are transmitted by deflectors from the control unit. The controlled object obtains information on its spatial position relative the centres of the rectangular laser rasters through a photodetector mounted on the control object. A displacement code correction unit is used, through which current angular coordinates of the controlled object and angular coordinates of the target are calculated and the environment is monitored and obstacles are searched for. Angular correction of the control field of the object is performed in accordance with the control program of the object contained in a deflector control unit, and data input thereto from the displacement code correction unit. The laser remote orientation system includes a displacement code correction unit which consists of an object video camera, an object position control unit, a target video camera and a target position control unit.;EFFECT: automatic control of the position of laser rasters for controlling an object.;4 cl, 1 dwg
