Abstract

The invention provides a portable fundus imaging system with the advantages of simple structure, small size and low cost and an imaging method thereof aiming at solving the problems of complex structure, large size and high cost of existing fundus cameras. According to the system, the imaging principle of the system is simple, fundus images can be rapidly acquired only by adding an external imaging system and an external light source system to existing mobile terminals (such as mobile phones and tablet PCs) with an photographing function, the system is simple in structure and small in size, carrying of the system is convenient, and the system can be carried by a doctor to another area to perform corresponding screening and inspection of fundus diseases; the using method of the system is very simple, the fundus images can be rapidly obtained by using a mobile phone to perform corresponding photographing operation, and special professional demands are not needed on operators; a 'switching' function of a light path is achieved by adopting a polarizer component to better filter out stray light generated by the reflection of an objective lens of an omentum and the edge of a cornea, so that the purpose of clear imaging is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a portable fundus imaging system and an imaging method thereof. Background technique [0002] The eyes are the "window of the soul", and it is the most important organ for people to obtain information. There are a large number of blood vessels distributed in the fundus. The morphological changes of these blood vessels can be used for early screening and diagnosis of various diseases such as hypertension, cerebrovascular sclerosis, diabetes, coronary arteriosclerosis, glaucoma, age-related macular degeneration, etc. It has become an important tool in modern medical diagnosis. means. [0003] The fundus camera is an important medical device for observing and recording retinal images. The existing fundus camera that has been disclosed has a large volume and a complicated structure, and is not convenient to be transported to the grassroots to carry out general survey and scre...
