Phase system, but external photographing unit not only makes structure complicated, loses portability, too increases cost.
A kind of hand-held fundus camera of the disclosure of the invention of Patent No. CN103815869A, this invention there is also inspection
What person observed on screen seems the image after photographic head and CCD or cmos image sensor process, it is impossible to directly see
The problem measuring real optical fundus optics real image.
A kind of visual digital ophthalmoscope of the disclosure of the invention of Patent No. CN102512137A, Patent No.
Somascope at the bottom of a kind of visual eye of the disclosure of the invention of CN103099600A, although both inventions can make the examiner directly observe
To real optical fundus real image, but they have all been equipped with single anti-digital camera to meet this condition, so considerably increase and set
Standby cost, is unfavorable for the popularization of equipment.
Summary of the invention
The present invention provide a kind of can be directly by eye fundus image digitized, the visual directly number of with low cost, simple in construction
Word ophthalmofundoscope, technical scheme is as follows:
A kind of visual Direct Digital ophthalmofundoscope, including the direct ophthalmofundoscope with adjustable LED shot-light, it is characterised in that
