Large field-of-view adaptive optics retinal imaging system and method with common optical path beam scanning

Abstract

A large field-of-view adaptive optics retinal imaging system and method with common optical path beam scanning, the system comprises: a light source module (), an adaptive optics module (), a beam scanning module (), a defocus compensation module (), a sight beacon module (), a pupil monitoring module (), a detection module (), a control module () and an output module (). The beam scanning module is configured in different scanning modes for carrying out different scanning imaging functions including a large field-of-view imaging function, a small field-of-view high-resolution imaging function and a large field-of-view high-resolution imaging function. The system is simple in structure, and the common optical path structure can obtain three types of retinal imaging images, which meets the requirements of different application scenarios and improves the application range of retinal imaging.
