Technical analysis on overall design of XXX panoramic sight

In order to enlarge the observation range,adopt the module units and raise the reliability, a multi-functional panoramic sight was designed. By using ballscrew and linear bearing, the lifting at its head was realized so that the observation range of the product could be enlarged. By using gear cluster differential technology, the moving transmission of the mirror was realized so as to guarantee the system reliability. Through driving the Dove prism with a step motor and the cooperation with the absolute value type photoelectric encoder to feedback the angular value position information, the image revolving during panoramic sighting was eliminated, so that the system observation and aiming accuracy and the angle-measuring accuracy could be guaranteed. Engineering practice shows that the panoramic sight can perform the following actions: observation aiming day and night, zooming continuously 3～6 at day, 300 mm lifting at its head, all panoramic sighting in azimuth, the angle-measuring accuracy is no less than 1 mard during continuous rotation.
