Abstract

The invention discloses an active implementation method for spherical motion detection. The method is characterized by including the following steps that a first joint, a second joint, a third joint,a fourth joint and a detector are sequentially connected and installed over a point light source, and the rotation axis of the first joint is made to coincide with the vertical optical axis of the point light source; the distance d between the point light source and the center point A of the second joint is calibrated; the first joint is rotated to make the detector conduct orientational rotation;and the second joint and the third joint are rotated to make the detector move on an arc with R as the radius and the point light source as the circle center, and the fourth joint is rotated to makea detection surface right face the point light source. The method has the advantages that a motion trajectory equation is established according to a trigonometric function, an accurate spherical motion trajectory is generated in a three-dimensional space, the spherical motion sphere diameter can be changed by adjusting the joint angle, and the application range is wide.

Description

technical field [0001] The invention relates to the field of spherical motion methods, in particular to a method for actively realizing spherical motion detection. 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 condition...
