Description
Technical field
This utility model relates to a kind of eyeground imaging system, particularly to a kind of EO-1 hyperion eyeground imaging system.
Background technology
Optical fundus refers to the bottom of eyes, the namely tissue of eyes bottommost.It includes the macula area on retina, optical fundus blood vessel, papilla of optic nerve, optic nerve fiber, retina, and postretinal choroid etc..If these positions occur pathological changes, it is referred to as retinopathy.
Retina is the thin film of a Rotating fields high complexity, and it is dispersed with substantial amounts of blood capillary, is the microvessel network of the deeper that uniquely can observe directly with non-wound in human body.Blood-vessels on human eye retina is observed, can be that doctor carries out many ocular disease, or even the diagnosis of general disease provides important evidence.The diseases such as such as hypertension, hyperlipidemia, nephropathy, diabetes, coronary heart disease, the change of its their early stage physiological status all can embody on optical fundus.
Whether diabetes, oculopathy, or some other cardiovascular disease, can check optical fundus along with the change of optical fundus state when PD, is timely discovery, the effective way of symptom management.The most effective examination of ocular fundus equipment mainly has five kinds: ophthalmoscope, slit lamp microscope, fundus camera, scanning laser ophthalmoscope, optical coherent chromatographic imaging etc..Five kinds of test modes are respectively arranged with feature.But considering Maturity, practical degree, operation complexity and the production cost of current technology development, fundus camera will be the examination of ocular fundus equipment being most widely used.
In traditional imaging technique, the difference of the optical characteristics of different materials depends on the grey level of artwork master and screens.Hereafter, on this basis, grow up use specific filter plate to extract the light of one or more groups specific wave band to carry out imaging analysis and characteristic research, here it is multispectral technology the earliest.And hyperspectral technique is to rise in the photoelectric detecting technology of new generation in 80 years 20th century.For high light spectrum image-forming is relative to multispectral imaging, the high spectrum image obtained by high spectrum imaging method has more rich image and spectral information compared with the multispectral image obtained by multispectral imaging.
High light spectrum image-forming technology is applied to ophthalmology and starts from the beginning of 21 century, to the optical Properties of eyeball, people show that optical fundus high light spectrum image-forming is feasible.Light incides optical fundus by eyeball, is first irradiated on retina, incides on choroid after some light transmission.Retina is mainly made up of neurocyte and glial cell, close to translucent；Choroid is mainly made up of vasoganglion, and containing a small amount of melanin, between retina and choroid, biological retinal pigment epithelium is mainly made up of melanin.And hemoglobin, melanin etc. have strong absorption and scattering process to light, it is ensured that the feasibility of optical fundus optical imagery；And its content and the spectral characteristic of Determines imaging, this provides foundation to utilizing high light spectrum image-forming technical Analysis optical fundus state.EO-1 hyperion fundus imaging is the new method of a kind of retinopathy non-invasive diagnosis, by obtaining optical fundus high spectrum image in real time, quickly effectively non-invasively can diagnose fundus oculi disease or other diseases retinal complication.
A kind of eye ground multi-optical spectrum imaging system based on line scanning of the disclosure of the invention of Patent No. 201110328132.3, uses grating beam splitting, realizes optical fundus multispectral imaging by spacescan.The method of spacescan is vulnerable to oculogyral impact.A kind of multi-channel retina spectrum imaging device of the disclosure of the invention of Patent No. 201010535168.4, uses Polarization Interference Filter to realize the collection of multi-channel spectral, but its spectral resolution is relatively low.At present, little to people's Eye irritation, spectral resolution is high, be the development trend in ophthalmic diagnosis field to the optical fundus high light spectrum image-forming technology that Rotation of eyeball is insensitive.
