VISUALISATION SYSTEM

FIELD: physics. ^ SUBSTANCE: said utility invention relates to the simulation equipment and is intended for the application in space modelling benches and simulators. The invention aims at drawing the quality of the simulated visual situation closer to the actual one and providing the simulation of the trained crew operation mode involving focusing of the observed image displayed on the VSK sight simulator screen during approach to and docking with the orbital station, at the most critical and dangerous section starting from a distance to the orbital station of 25 m and closer. This result is achieved due to the fact that, according to the invention, the visualisation system contains a sight simulator output screen with a linear motion suspension and a longitudinal suspension position monitoring sensor; the screen is optically coupled with two parallel optical projection systems, the first of which (the central channel system) contains the following components installed in series along the optical axis of the sight simulator: an optical system, a rear projection screen, a reflecting mirror for rotating the optical axis of the projection by 90 degrees, an optical coupling device, a video projector projecting the visual situation image to the rear projection screen and electrically coupled with the central channel image generator; while the second system (the peripheral channel system) contains the following components installed in series along the optical axis of the sight simulator: eight optical systems located at equal distances around the optical system of the central channel, eight rear projection screens, an optical coupling device, a video projector projecting the visual situation image to the rear projection screens and electrically coupled with the peripheral channel image generator; the rear projection screen of the central simulator channel, the mirror for rotating the optical axis of the projection by 90 degrees, the central channel optical coupling device, and the central channel video projector are installed on an additional rack that may be moved linearly in parallel to the optical axis of the VSK sight simulator using an additionally introduced servo drive; besides that, the following components are additionally introduced in the visualisation system: a drive control unit, a digital-to-analogue converter, a defocusing mode modelling unit, an approach and docking parameter modelling unit, an image generator control unit, an analogue-to-digita
