Abstract
The utility model relates to a three-dimensional optical lighting system, which aims to provide a lighting system with a wide range of resolution and wide application range of sweep objects, through which uneven surfaces can be clearly seen. The technical scheme of the utility model is that the three-dimensional optical lighting system comprises a three-dimensional light source system, a orientation spectroscope and a reflection imaging light path system. The light with even wide angle generated from the three-dimensional light source system permeates the orientation spectroscope and irradiates the effective scanning area. The imaging light reflected by the lighting object is reflected by the orientation spectroscope and turns and enters into the lens set of the reflection imaging light path system and finally reaches to the CCD image system of the reflection imaging light path system.
