Abstract

The invention relates to a miniature light source, and specifically relates to a miniature light source system for interventional lighting. In order to solve the technical problems that the electronicendoscope has complex process and high manufacturing cost, but the laser confocal endoscope cannot be used for hyperspectral imaging and the inspection accuracy is not enough, the invention providesa miniature light source system for interventional lighting. A miniature light source system for interventional illumination includes a wide-band light source collimation system for hyperspectral imaging illumination, a beam conversion system that converts parallel cylindrical beams into an annular hollow beam, and an annular ball lens array system that couples parallel annular beams into an arrayof light transmitting fibers. The auxiliary light source system of the invention for interventional optical imaging or hyperspectral imaging can be applied to biomedical and clinically detected optical imaging or hyperspectral imaging technology.

Description

technical field [0001] The invention relates to a miniature light source, in particular to a miniature light source system for interventional lighting, which can be used as an auxiliary light source system for interventional optical imaging or hyperspectral imaging. Background technique [0002] The micro-light source system of interventional lighting can be applied to the diagnosis technology of liver cancer in micro-hyperspectral imaging to realize the early detection of cancer. Auxiliary lighting for imaging purposes. [0003] At present, the endoscope systems that can be used for liver cancer detection mainly include electronic endoscopes, fluorescent confocal endoscopes and laser confocal endoscopes. Among them, the image of the electronic endoscope is clear, but the preparation process is complicated and the preparation cost is high. The light source systems used in the latter two endoscopes both use confocal technology. The light source used in the fluorescent confoc...
