Embodiment
[0030] A movable two-degree-of-freedom photoelectric target device such as figure 1 shown. The whole device adopts a U-U structure, and is divided into inner frame 4, outer frame 3, support 1 and chassis 7, etc., and the two frames can move independently or in linkage. The collimator simulating the photoelectric target is installed on the fixture 5 on the inner frame 4, and the inner frame 4 and the outer frame 3 rotate to rotate with the collimator, thereby realizing a two-degree-of-freedom photoelectric target for azimuth and pitch rotation. One end of the inner frame 4 is installed with a counterweight 6 for balancing the weight of the collimator on the fixture 5 . Both the inner frame 4 and the outer frame 3 are driven by torque motors, and a precision photoelectric encoder disc is installed on the inner frame shaft 8 and the outer frame shaft 2 to measure the rotation angle of the inner and outer frames, so that the photoelectric target (parallel light pipe) azimuth and...

The invention discloses a movable two-freedom-degree photoelectric target. The movable two-freedom-degree photoelectric target is in a U-U structural style and comprises a support, an outer frame, aninner frame and a chassis. The support is of a U-shaped structure, and the open end is fixed to the chassis. The outer frame and the inner frame are each of a U-shaped structure, arranged in an intersected mode, and located in the support. The outer frame and the inner frame can be rotated around an outer frame rotating shaft and an inner frame rotating shaft correspondingly. The closed end of theinner frame is provided with a clamp for installation of a collimator which simulates the photoelectric target. The open end of the inner frame is provided with a balancing weight used for balancingthe weight of the collimator on the clamp. The chassis is located at the bottom end of the whole device and used for installation of tested photoelectric tracking equipment. The movable two-freedom-degree photoelectric target can be used for simultaneously testing the position and pitch tracking performance of the photoelectric tracking equipment, the testing process is low in cost and free of limitation of sites, and the movable two-freedom-degree photoelectric target can be transported to a site where the tested equipment is located for use, and meets emergency testing requirements.
Description
technical field [0001] The invention belongs to the technical field of photoelectric testing, and in particular relates to a movable double-degree-of-freedom photoelectric target for measuring the performance of photoelectric tracking equipment. Background technique [0002] In the development and maintenance process of photoelectric tracking equipment, moving photoelectric targets are needed to test the tracking performance of photoelectric tracking equipment. [0003] Among the existing test methods, one is to provide real-field photoelectric targets, such as airplanes flying in the air, ships sailing at sea, etc., for testing photoelectric tracking equipment. This kind of testing means is costly, and is generally only used in equipment type testing, and is not suitable for testing in the development or maintenance of photoelectric tracking equipment. [0004] Another method is to install a collimator on a rotatable arm suspended on the beam to simulate a distant rotatabl...
