Abstract

The invention discloses a high-spectrum fundus imaging system, and aiming at providing a multi-spectrum fundus imaging system which has the advantages that the structure is simple, the influence of oculogyration is avoided, and multiple spectrums of the whole fundus can be obtained only through one time of operation. The multi-spectrum fundus imaging system comprises a light beam generating module (1), a light splitting part (2), an imaging module (3) and an output module (4). Light beams are generated by the light beam generating module (1) and reflected to the human fundus through the light splitting module (2), the light beams are reflected by a fundus tissue structure to transmit the light splitting part (2) to reach the imaging module (3) to form an intermediary image, and finally further processing, imaging and outputting are carried out through the output module (4). Multi-band light splitting or dual-display light splitting or dual-display multi-band light splitting is adopted for the output module (4). The multi-spectrum fundus imaging system is applied to the technical field of fundus imaging.

Description

technical field [0001] The invention relates to a fundus imaging system, in particular to a multispectral fundus imaging system. Background technique [0002] The fundus refers to the bottom of the eye, which is the tissue at the bottom of the eye. It includes the retina, fundus blood vessels, optic nerve head, optic nerve fibers, macula on the retina, and choroid behind the retina. If lesions occur in these parts, they are collectively referred to as fundus diseases. [0003] The retina is a thin film with a highly complex structure, and a large number of capillaries are distributed on it. It is the only deep microvascular network in the human body that can be directly observed without trauma. Observing the vascular veins on the retina of the human eye can provide an important basis for doctors to diagnose many eye diseases and even systemic diseases. For example, hypertension, hyperlipidemia, kidney disease, diabetes, coronary heart disease and other diseases, the chang...
