Abstract

The invention discloses an image light source. The light source is a pipe light source. An opening is formed in the lower portion of the circumferential wall of the pipe light source. A long-strip-shaped notch is formed in the upper portion of the circumferential wall of the pipe light source and extends in the axis direction of the pipe light source. According to the imaging light source, bright strips and dark strips are avoided, interference strips similar to rainbows are prevented from happening to an image formed when light rays penetrate through the notch, and imaging quality is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an imaging light source. Background technique [0002] At present, in the printing inspection industry, it is impossible to obtain ideal imaging of laser rainbow holographic prints by using ordinary strip-shaped white light sources. Ordinary imaging methods are limited by the diffraction characteristics of laser rainbow holography, and rainbow patterns will be produced when white light imaging is irradiated. The resulting rainbow pattern interferes a lot with the detection, so it is very important to find a new light source to solve this problem. Contents of the invention [0003] The present invention aims at solving one of the above technical problems at least to a certain extent or at least providing a useful commercial choice. Therefore, an object of the present invention is to provide an imaging light source that improves the imaging effect. [0004] According t...
