Embodiment 1

[0030] Such as figure 2 Shown is a handheld multi-spectral fundus imaging device, which includes a hand-held housing in which an eyepiece 205, a light source 201 for generating multi-spectrum, and a single-pixel detector 208 for imaging are arranged. On the optical path from the light source 201 to the eyepiece 205, an optical filter 202, a focusing lens 203, and a dichotomous mirror 204 are sequentially arranged; There is a beam splitter group 206 and a spatial light modulator 207 . Wherein, the light source 201 is used to generate a multi-spectral light source including near-infrared band spectrum. Specifically, in this embodiment, the light source may be a xenon lamp light source or an array LED light source, and the optical filter 202 is used to filter out light with a wavelength of 420-890nm. Light source 201, optical filter 202, focusing lens 203, dichotomous mirror 204 and eyepiece 205 constitute the illumination light path 1 of the imaging device, and the emitted li...

Abstract

The invention relates to the technical field of multispectral fundus imaging which can be widely applied to the aspects of ophthalmic imaging, medical diagnosis and the like, and particularly relatesto a hand-held multispectral fundus imaging equipment and system. The equipment comprises a shell, a light source which is provided with an eyepiece and used for generating multispectral light, a single-pixel detector used for imaging and an interactive module used for performing data interaction with a computer; an optical filter, a focusing lens and a second storyboard; a beam splitter group anda spatial light modulator are arranged on a light path from the light source to the eye piece in sequence. Convenience is brought to carrying, imaging is rapid, and the picture resolution is high.

Description

technical field [0001] 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. It specifically relates to a handheld multispectral fundus imaging device and system. Background technique [0002] There are a large number of various pigments in the human eye, and different pigments absorb light of different wavelengths differently (see figure 1 ), and the different distribution of these pigments in the eye leads to different penetration capabilities of the tissues for light waves, so multispectral imaging (MSI) uses this characteristic to obtain images of different tissue layers and tissue structures of the fundus. Eye lens, hemoglobin, zeaxanthin, lutein, rhodopsin and other absorption wavelengths are in the spectrum of 450nm-600nm, and melanin absorption wavelength is above 600nm. The spectrum of different wavelengths can reflect the fundus structure at the corres...
