Active two-dimensional tracking collimator

Abstract

The invention relates to an active two-dimensional tracking collimator. The collimator consists of a base, a body frame, a telescope system, an electric control system, a visual image acquisition mechanism, a direction driving mechanism and a pitching driving mechanism, wherein the electric control system, the direction driving mechanism and the pitching driving mechanism are arranged in the body frame; the visual image acquisition mechanism is fixedly arranged on the telescope system; the telescope system is fixedly arranged on the upper part of the outer side of the body frame; and the electric control system is connected with the visual image acquisition mechanism, the direction driving mechanism and the pitching driving mechanism through data lines. The direction driving mechanism and the pitching driving mechanism realize two-dimensional (direction and pitching) movement of the collimator and the electric control system and the visual image acquisition mechanism realize two-dimensional (direction and pitching) information recognition of the collimator. In the telescope system of the invention, a normal of a target prism and a collimation deviation angle of an optical axis of the collimator are measured and subdivided by adopting a position sensitive device (PSD), so that the direction of the prism can be actively tracked and measured in real time.

Description

technical field [0001] The invention relates to a collimator, in particular to an active two-dimensional tracking, which belongs to the technical field of photoelectric measurement. Background technique [0002] The collimator currently used in the ground aiming system of the launch vehicle works by operating on-site by the operator to realize the long-distance photoelectric collimation of the prism of the rocket platform. dimensional (azimuth and pitch) tracking targeting capability and rocket targeting capability under wind swing. At the same time, the photoelectric collimation system of the collimator uses silicon photocells as the photosensitive device, and does not have the ability to measure the collimation deviation angle. Therefore, the collimator in active service can only perform collimation calibration on the rocket platform prism through the method of changing.

[0002] The collimator currently used in the ground aiming system of the launch vehicle works by operating on-site by the operator to realize the long-distance photoelectric collimation of the prism of the rocket platform. dimensional (azimuth and elevation) tracking targeting capability and rocket targeting capability under wind swing

At the same time, the photoelectric collimation system of the collimator uses silicon photocells as the photosensitive device, which does not have the ability to measure the collimation deviation angle. Therefore, the collimator in active service can only perform collimation calibration on the rocket platform prism through the method of change.

[0003] However, the movable launch platform of the new generation of launch vehicles does not have the function of turning, and the initial azimuth deviation (range of about ±2°) of the prism on the arrow cannot be adjusted by rotating the launch platform. The prism on the arrow can only be adjusted within the area covered by the initial azimuth deviation of the prism. Active search and capture, the initial orientation method of the strapdown inertial group is adopted on the arrow, that is, the inertial group prism is rigidly connected to the arrow body, and the prism cannot be rotated and leveled
