Abstract
A fundus optical image device includes a light source, a first optical element set and a second optical element set. The first optical element set includes a first diaphragm. The light emitted from the light source passes through the first diaphragm and reaches a fundus through the first optical element set. The second optical element set includes a second diaphragm. The light is reflected by the fundus and then passes through the second diaphragm to present an image of the fundus. At least one of the first diaphragm and the second diaphragm is a microarray diaphragm.
Claims10
A fundus optical image device, comprising:
- a light source emitting a light;
- a first optical element set comprising a first diaphragm and a spectroscope, wherein the light emitted from the light source passes through the first diaphragm and the spectroscope and then reaches a fundus through the first optical element set;
- and
- a second optical element set comprising a second diaphragm and a first lens, wherein the light is reflected by the fundus and then passes through the spectroscope, the first lens and the second diaphragm in order, thereby presenting an image of the fundus;
- wherein, at least one of the first diaphragm and the second diaphragm is a microarray diaphragm, the first lens is disposed between the spectroscope and the second diaphragm;
- wherein the microarray diaphragm has a plurality of switch units, and each of the plurality of switch units is controlled by a voltage to change its color and transmittance.
