Embodiment Construction

[0061] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0062] see first figure 1 , figure 1 Shown is a schematic diagram of the working principle of the dynamic photoelectric autocollimator. Along the direction of the horizontal optical axis, the beam emitted by the laser A1 is converged by the condenser lens A2 and then illuminates the reticle A3, where A3 is located at the focal plane of the collimating objective lens A5, and the beam passing through the reticle A3 passes through the beam splitting prism and the collimating objective lens in turn Finally, a parallel beam output is formed, where the beam-splitting surface of the beam-splitting prism forms an angle of 45° with the horizontal optical axis. The output parallel light beams are reflected by the mirror A6 under test and are imaged on the photodetection device P af...

Abstract

The invention relates to a device and method for detecting the dynamic properties of a two-dimensional directional mirror. The device comprises a dynamic photoelectric autocollimator, a controller of the dynamic photoelectric autocollimator, a hollow rotary platform, a controller of the hollow rotary platform, a rotary target, an adjustment platform, a data acquiring and processing system and a computer measurement and control system. Under the guidance of the computer measurement and control system, a target simulation reflector on the rotary target is driven by the rotary platform to simulate an optical target in movement, the dynamic photoelectric autocollimator provides the rapid and high-precision angle miss distance for the two-dimensional directional mirror, the data acquiring and processing system feeds back and controls the two-dimensional directional mirror to track the target simulation movement in real time, and the computer measurement and control system processes the measurement data of the photoelectric autocollimator in real time to obtain the data reflecting the dynamic response properties of the two-dimensional directional mirror. The device and method provided by the invention can be used for detection of properties of the two-dimensional directional mirror, such as axis shaking, step response, dynamic continuous tracking and the like.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to a dynamic performance detection device and a detection method of a two-dimensional pointing mirror. The invention can be used for indoor detection and verification of the static and dynamic performances of large-angle beam guiding devices such as two-dimensional pointing mirrors. Background technique [0002] Photoelectric capture, tracking and targeting technology has important applications in the fields of laser radar, free space laser communication, and photoelectric countermeasures. From the perspective of system structure and rotation characteristics, the tracking and aiming frame can be divided into two categories: one is the rotating frame, that is, the entire telescope system is installed on the universal bracket, and the frame needs to be rotated when tracking and aiming at the target; the other is It is a rotating pointing mirror (also known as a scanni...
