Problems solved by technology

The traditional fundus camera uses a camera to obtain an image of the entire fundus. Because the fundus has curvature and reflections, an optical path system composed of one or more aspheric mirrors must be used. Aspheric mirrors are expensive, resulting in high equipment costs. And The shooting angle is limited and the shooting area is small

Abstract

The invention provides a compound eye fundus camera which is large in shooting zone and lower in cost. The compound eye fundus camera comprises a light path system, wherein the light path system comprises multiple image acquisition units and a compound eye lens arranged in front of the multiple image acquisition units, and the multiple image acquisition units respectively correspond to one zone of the fundus. The compound eye lens is provided with multiple lens units, each image acquisition unit rightly faces one lens unit, and the lens units are spherical mirrors. Each image acquisition unit comprises a camera module for acquiring fundus image corresponding to the zones and an illumination module for providing illumination for the camera modules of other or all the image acquisition units, wherein the camera modules are arranged between the corresponding lens units and the illumination modules.

Description

technical field [0001] The invention belongs to ophthalmic equipment, in particular to a compound eye fundus camera. Background technique [0002] The fundus camera is one of the commonly used equipment in ophthalmology. It is used to observe the fundus to judge whether there is a lesion in the fundus. The traditional fundus camera uses a camera to obtain an image of the entire fundus. Because the fundus has curvature and reflections, an optical path system composed of one or more aspheric mirrors must be used. Aspheric mirrors are expensive, resulting in high equipment costs. And The shooting angles are limited and the shooting area is small. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a compound eye fundus camera, which has a large shooting area and low cost. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [...
