Abstract

The invention provides a multispectral light source and a fundal imaging system and relates to the technical field of fundal imaging. The multispectral light source includes a laser bundle and frostedglass; the laser bundle is formed by coupling a plurality of laser sources different in wavelength and fiber bundles; a beam from the laser bundle is transformed into an extended source via the frosted glass. The laser sources different in wavelength form the multispectral light source which has good laser alignment and may be efficiently coupled to fibers; laser is conducted to the emitting endvery conveniently through the fibers; multispectral lighting of fundus is achieved.

Description

technical field [0001] The invention relates to a fundus imaging system, in particular to a multi-spectral light source and a fundus imaging system. Background technique [0002] Fundus imaging technology is an important method for ophthalmic disease examination. Retinal vascular abnormalities represent the systemic microvascular lesions to a certain extent, and are the pathological basis of target organ damage in metabolic syndrome. The retinal microcirculation system is very similar to the blood circulation system of the heart, brain, kidney and other organs in terms of structure and function, and can objectively reflect the development and changes of systemic diseases. Many people have developed corresponding fundus diseases before clinical symptoms appear. Abnormal manifestations also indicate that some fundus abnormalities can appear before subjective symptoms. There are many types of diseases that cause fundus changes, and most of them develop insidiously, and there i...
