Embodiment Construction

[0041] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0042] The laser target simulation device of the present invention is such as figure 2 As shown, the optical axis of the laser 6, the energy adjustment device 7, the beam expander 8, and the prism 10 are on the same straight line as the rotation axis of the electronically controlled rotary table 9.

[0043] The structure of the electronically controlled rotary table 9 is as image 3 As shown, it is composed of a motor 9-1, a table body fixing part 9-2, and a table body rotating part 9-3. The rotating shaft of the motor 9-1 forms a transmission relationship with the table rotating part 9-3 through a transmission mechanism installed inside the table fixing part 9-2. The rotating part of the table body 9-3 is hollow and has a certain space for installing the prism. The electronically controlled rotating table angle output device can outp...

Abstract

The invention discloses a device simulating a laser target of small-angle movement, which comprises an optical part and an electric-control part, wherein the optical part comprises a laser, an energy regulator, a beam enlarger and a prism, and the electric-control part comprises an electric-control rotary table device and a controller and an angle-output device thereof. A light beam sent by the laser is radiated into the beam enlarger by the energy regulator, a radiated light ray is deviated by the central prism of the electric-control rotary table and enters a tested optical-electrical tracking system, and parallel light rays can be controlled to rotate according to a certain deviated angle to simulate a moving target by controlling the electric-control rotary table. The invention has compact structure, simple installation and regulation, low cost and easy calculation of the simulated target position, and can be used for the indoor tests of the aerospace and military small-angle optical-electric tracking systems.

Description

Technical field [0001] The invention relates to photoelectric instrument testing technology, in particular to a device for simulating a small-angle moving laser target, which is used for the performance test of an indoor small-angle photoelectric tracking system. Background technique [0002] In the field of photoelectric tracking technology, the testing and performance evaluation of photoelectric tracking system is an important part of its development. In the indoor test of the photoelectric tracking system, a certain device is often used to simulate the movement of the target in the space, and the measured photoelectric system is turned on to complete the tracking, and the tracking results are recorded and analyzed to evaluate the tracking performance of the photoelectric tracking system. Whether the motion characteristics and optical characteristics of the simulated target are real has become the difficulty of the test system. [0003] The existing target simulation methods mai...
