Description

technical field [0001] The invention relates to the field of image plane debugging of aerospace full-spectrum zoom lenses, in particular to a zoom lens automatic image plane docking and optical axis runout detection system and a method for using the same. Background technique [0002] The existing image plane docking methods are generally divided into two categories. The first type of artificial image plane docking method is to find the position of a clear image plane by continuously correcting the thickness of the image plane trimming pad. This method requires at least 2 -3 people work at the same time, which is relatively labor-intensive, and the image clarity of different batches of products may vary. The second type is the semi-automatic image docking method, which can be driven by a motor to realize image docking. Compared with manual image docking, the image docking efficiency of this method is improved, but whether the image is In terms of clear discrimination, multi...
