Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing, as figure 1 Shown:

[0028] The camera to be docked is placed on a mobile platform with a grating ruler, and the flange of the lens to be tested is connected to the camera to be docked. At this time, the laser power supply is powered on, and the light emitted by the He-Ne laser is collimated by the standard lens and becomes The outgoing parallel light, which is reflected by the dichroic prism, is incident on the lens under test, and converges at the focal plane of the lens under test after passing through the lens under test. When the laser beam reflected by the focal plane passes through the lens under test again, the emitted light is still parallel light, and the parallel light is incident on the 45°reflecting prism in parallel after passing through the beam splitting prism. According to the total reflection theorem of light, the parallel light at this time The incident angle...

Abstract

The invention provides a camera focal plane fast aligning method and device using visible light. The camera focal plane fast aligning method and device mainly solves the problem in the prior art that efficiency is low and precision is poor during focal plane aligning. The camera focal plane fast aligning device comprises a camera and a tested lens connected with the camera and further comprises a parallel light emitting mechanism, a beam splitter prism and a reflecting prism. The camera focal plane fast aligning device provides precision guarantee for an aviation spaceflight various camera focal plane butting process, improves assembling efficiency of the process, is especially suitable for production and developing tasks for massive products, and guarantees that the camera can obtain a good imaging effect finally.

Description

technical field [0001] The present invention provides a quick alignment method and device, and in particular relates to a visible light camera focal plane alignment method and device, which are mostly used in the field of aviation and aerospace airborne imaging. Background technique [0002] Cameras are important payloads of various aviation and aerospace vehicles, providing video images and picture images for various tasks. In the process of camera production and development, the process of accurately docking various detectors with the focal plane position of the lens is a prerequisite step to ensure the imaging quality. When a large number of cameras are produced at the same time, how to quickly complete the production process is to ensure the production and development tasks. The key to being able to finish on time is even more important. [0003] In the process of camera production and development, the image plane docking is the last step of optical machine assembly. Th...
