SYSTEM OF IMAGE STABILIZATION ON MOBILE BASE Russian patent published in 2004 - IPC

FIELD: optical instrumentation. SUBSTANCE: invention is related to gyrostabilized facilities put on mobile objects. System of image stabilization has indicator gyroscopic platform with mirror set on it, gimbal suspension in the form of external and internal frames, free gyroscopic angle-data transmitter with torque generators, transmitters of angle of rotation of rotor of gyroscopic angle- data transmitter which outputs are connected through amplification-correction devices of corresponding stabilization channels to inputs of stabilization sensors of suspension frames, two channels of control over rate of turn of platform with amplification link in each channel connected to input of proper torque generator of gyroscopic angle-data transmitter, two threshold units for protection of rotor of gyroscopic angle-data transmitter from impact against mechanical rests connected with their inputs to transmitters of angle of rotation of gyroscopic angle-data transmitter and with their outputs to first inputs of amplification link of channel of control over rate of turn of platform through adders and two units protecting stabilization sensors against overheating connected to amplification-correction device of each stabilization channel. Free gyroscopic angle-data transmitter is mounted on auxiliary axle that is coupled to mirror by means of belt transmission with gain factor 1:2. System includes device to compensate for errors of belt transmission, two units protecting torque generators of gyroscopic angle-data transmitter against overheating, two devices to compensate for drift of line of sight and transmitters of vertical and horizontal guidance angles. EFFECT: increased precision of stabilization and speed of control over free gyroscopic angle-data transmitter. 4 dwg
