| description | In order to solve the problem of illumination uniformity, the invention provides a composite illumination device and a multi-sensor detection system, the composite illumination device comprises an illumination light source, an aspherical lens and a free-form surface lens, the illumination light source is used for emitting illumination light, and the illumination light provides uniform illumination for a detection area after passing through the aspherical lens and the free-form surface lens; the incident plane of the free-form surface lens is a plane, the emergent plane of the free-form surface lens is a free-form surface, the free-form surface is a polynomial free-form surface, and the polynomial free-form surface is designed by adopting an xmyn-term quadric surface. The illumination device can be applied to a damaged precursor machine vision detection system in a laser additive manufacturing process to serve as the illumination device, and the illumination system has high illumination uniformity within a sho |
