Retinal imaging system scanning with confocal light beam

摘要

In the retinal imaging system scanning with a confocal light beam, a light source module (1), an adaptive optical module (2), a light beam scanning module (3), a relay module with a narrow field of view (5), and a relay module with a wide field of view (6) , A target module 9, a pupil monitoring module 7, a detection module 8, a control module 10, and an output module 11. The system corrects eye aberration in real time using adaptive optical technology, sets the synchronous scanning of the light beam, and combines two sets of relay optical path structures, a narrow field of view and a wide field of view, to confocal a wide field of view. It can realize the scanning imaging function and the adaptive optical high-resolution imaging function of a narrow field of view at the same time. The system can observe the disease lesion area of the retina in a large range through imaging of a wide field of view, as well as observe the microstructure of the lesion through high-resolution imaging of a narrow field of view, and also perform optical beam scanning of a common optical path. Through this, it is possible to obtain various imaging images to satisfy various usage scenarios, greatly expanding the application range of the existing confocal imaging device.
