Embodiment Construction

[0041] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0042] Laser target simulation device of the present invention 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 electric control rotary table 9 .

[0043] The structure of the electric control rotary table 9 is as follows: 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 motor 9-1 constitutes the transmission relationship with the table body rotating part 9-3 through the transmission mechanism installed inside the table body fixed part 9-2. The interior of the table body rotating part 9-3 is hollow and has a certain space for installing the prism. The electronically controlled rotary table angle output device can...

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 a photoelectric instrument testing technology, in particular to a device for simulating a small-angle moving laser target, which is used for performance testing 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 space, and the photoelectric system under test is turned on to complete the tracking, and the tracking results are recorded to analyze and evaluate the tracking performance of the photoelectric tracking system. Whether the motion characteristics and optical characteristics of the simulated target are realistic or not has become the difficulty of the test system. [0003] The existing target simul...
