Abstract

The invention discloses a method for adjusting a lens array, the lens array comprises at least two lens units which are transversely arranged side by side, and the method comprises the following steps of: cutting off a part of each lens unit, and further adjusting the center-to-center distance and the optical center distance of the light passing surface of each lens unit according to actual requirements. A part of each lens unit is ground and cut off, after grinding and cutting, the center distance of the light passing surface and the optical center distance of each lens unit can be changed, the center distance of the light passing surface of each lens unit is changed, and the parallax (visual difference) between images formed by each lens unit is also changed, so that the parallax adjustment and the optical center distance change of each lens unit are realized; according to the optical system, the relative position of the image formed by the emergent light of each lens unit on the optical sensor (CMOS) is also changed, the effective utilization of the area of the optical sensor (CMOS) is realized, the size of the lens units after grinding and cutting is reduced, the lens units can be spliced together more compactly, and the size of the optical system can be reduced.

Description

technical field

[0001] The present invention relates to the technical field of imaging devices, in particular to a method for adjusting a lens array. Background technique

[0002] The lens array can be used for 3D imaging (two-lens imaging) and light field imaging (multi-lens imaging), which mainly separates the light from several viewing angles through several lens units arranged side by side to improve the stereoscopic effect of imaging.

[0003] The distance between the centers of the light-passing surfaces of each lens unit of the lens array will affect the parallax of imaging. Specifically, increasing the center-to-center distance of the light-passing surfaces of each lens unit can increase the parallax and reduce the center-to-center distance of the light-passing surfaces of each lens unit. Parallax will be reduced, and the optical center spacing of each lens unit of the lens array will affect the position of the image formed by the outgoing light in the optical sensor...
