Title: Innovations of Chaohong Li in Fundus Imaging Technology

Introduction

Chaohong Li is a prominent inventor based in Suzhou, China, known for his significant contributions to the field of medical imaging technology. He holds three patents that showcase his innovative approach to fundus imaging devices. His work has the potential to enhance diagnostic capabilities in ophthalmology.

Latest Patents

One of his latest inventions is the confocal laser fundus angiographic device. This device comprises an objective lens, a scanning lens, a scanning galvanometer, a mirror, a filtering module, an imaging detection assembly, and an excitation light source. The illumination light emitted by the excitation light source enters the fundus after passing through the scanning galvanometer, scanning lens, and objective lens. Fluorescent substances in fundus vessels are excited by the illumination light, emitting light with a specific wavelength. This light then enters the imaging detection assembly after passing through various components, including a filtering module that automatically switches filters, thus preventing operator errors.

Another notable invention is the ultra wide field fundus imaging system. This system includes a photosource, an optical splitter, a scanning assembly, a curved reflector, a probe pinhole, and an imaging assembly. The scanning assembly features two scanning mirrors that work together to achieve wide field imaging. The light emitted by the photosource is reflected through several components before entering the fundus, where it is reflected by the retina and returned to the imaging assembly. This innovative design effectively avoids ghost images and improves imaging quality.
