Document Type and Number:
WIPO Patent Application WO/2020/073187
Kind Code:
A1
Abstract:
An eye fundus image detection apparatus, comprising a first sensor (1), an optical grating (2), a beam splitter (6), and a variable lens component which are located on a first optical axis and arranged in sequence, a first light source (3), a first light condenser (4), and a first light splitter (5) which are located on a second optical axis and arranged in sequence, a second sensor (11), a second light condenser (10), a second light splitter (8), and a third light splitter (7) which are located on a third optical axis and arranged in sequence, and a second light source (13) and a third light condenser (12) which are located on a fourth optical axis and arranged in sequence. The diopter of the variable lens component is controlled by a voltage, and focusing of the first light source (3) is synchronized with that of the second light source (13). The apparatus may simultaneously capture images of the crystalline lens and the eye fundus, less damage is made to the human eyes by a focusing operation, the change of the diopter of the variable lens component is coherent, and the accuracy of image capture is high.
