Abstract

The invention discloses a spherical surface motion mechanism. The spherical surface motion mechanism comprises a first joint, a first arm, a rotating mechanism capable of adjusting the height and inclination angle of a detector and the detector, wherein one end of the first arm is rotationally connected with the first joint, the other end of the first arm is connected with one end of a rotating mechanism, the other end of the rotating mechanism is rotationally connected with the detector, the first joint is located over a point light source, the rotation center axis of the first joint coincides with the vertical optical axis of the point light source, and the front face of the detection face of the detector faces the point light source. The spherical surface motion mechanism has the beneficial effects that the detector moving along a spherical surface which takes the point light source as a sphere center and has a variable sphere diameter is realized, the structure is simple, the required space is small, and the weight is light.

Description

technical field [0001] The invention relates to the field of spherical sports, in particular to a spherical sports mechanism. Background technique [0002] Spherical motion is an important part of the target optical characteristic measurement system and the optical imaging guidance seeker performance test system based on hardware-in-the-loop simulation. In the target optical characteristic measurement system, in order to realize the optical characteristic measurement of different illumination directions and observation directions, the light source and the measurement target are generally fixed, and the position of the detector or the measurement target or the pitch angle of the detector in the detection direction needs to be changed. In the performance test system of the optical imaging guidance seeker, the hardware-in-the-loop simulation technology is used to simulate the movement characteristics of the target under laboratory conditions, so as to test the tracking performa...
