The invention relates to the technical field of fundus multispectral imaging, and can be widely used in biomedical ophthalmic imaging, medical diagnosis and the like. Specifically, the invention relates to a handheld multispectral fundus imaging device and system. It includes: a housing with an eyepiece, a light source for generating multispectral light, a single-pixel detector for imaging, and an interaction module for data interaction with a computer; the light from the light source to the eyepiece An optical filter, a focusing lens, and a bisecting mirror are arranged on the road in sequence; a beam splitter group and a spatial light modulator are arranged in sequence on the optical path from the bisecting mirror to the single-pixel detector. Easy to carry, fast imaging, and high image resolution. |
