Optical path adjustment method and optical path adjustment device

Abstract

The invention discloses an optical path adjustment method and an optical path adjustment device. The optical path adjustment method is used to adjust the optical path in optical equipment. The optical equipment includes a light source and a lens. The lens is located on the outgoing light path of the light source. When the imaging beam emitted by the light source After being transmitted through the lens, a first spot is formed on the imaging plane; the optical path adjustment method includes the following steps: obtaining the relationship between the spot size of the corresponding model of the lens and the imaging distance; according to the relationship between the spot size and the imaging distance, determining the first axial position of the lens in the optical axis direction, and adjust the lens to the first axial position; acquire the first size of the first light spot when the lens is located at the first axial position; according to the first size and the size of the light spot and the imaging Adjust the axial position of the lens in the direction of the optical axis until the imaging beam is focused on the imaging plane. The technical scheme of the invention improves the assembly yield and efficiency of the optical equipment.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical path adjustment method and an optical path adjustment device. Background technique [0002] In the assembly of optical equipment, the position of each optical element has high precision requirements, especially with the development of technology, the volume of optical equipment itself is further reduced, resulting in further improvement of assembly accuracy. When assembling optical equipment, it is necessary to adjust the position of each optical component so that the imaging beam can reach a focused state in the optical path, so as to ensure the clarity of the collected or displayed image. At present, optical equipment is usually assembled manually or semi-automatically, which is highly dependent on experience, lacks systematicness, and is difficult to guarantee accuracy and stability. The assembly yield and assembly efficiency of optical equipment are very low. Co...
