More Information
Summary:An illumination system comprises a laser light source, a fluorescent color wheel, a first light detection module, a first light sensing assembly and a controller. A first color zone boundary is arranged between the first color zone and the second color zone of the fluorescent color wheel. The first light detection module emits a first detection light beam. The first light sensing assembly is located at the downstream of the light path of the fluorescent color wheel. The controller is electrically coupled to the first light detection module and the first light sensing assembly, and the controller stores reference color time sequence information. In the period when the first color area is switched to the light path of the laser beam, the laser beam penetrates through the first color area, and first laser beam time sequence information is sensed by the first light sensing assembly. The controller determines a first displacement value between the first label and the first color zone boundary according to the firs
