The invention relates to a fundus optical full-field microangiography imaging device and method. The device comprises a fundus illumination
optical path, a fundus imaging
optical path, a synchronous triggering source and a
data processing system, wherein the fundus illumination
optical path and the fundus imaging optical path are synchronously triggered by the synchronous triggering source; the fundus illumination optical path comprises a
light source controller, a
laser light source, a beam expanding lens, a
beam splitter lens and an eye piece objective lens which are sequentially connected; and the fundus imaging optical path comprises an eye piece objective lens, a
beam splitter lens, an imaging ocular lens, a lens and a COMS (Complementary
Metal Oxide Semiconductor) camera which are sequentially connected. The device and the method have the advantages that the
light source gives out
laser at the same frequency as the sampling
frame rate of the camera; the realization of the fundus
microvessel imaging is ensured; and meanwhile, the
laser power is reduced, so that the value reaches the range capable of being borne by human eyes. The method and the device can realize the fundus optical full-field microangiography imaging. The method has the advantages that a contrast agent is not needed; the resolution ratio, the
signal-to-
noise ratio and the detection depth are high; and the fundus
blood capillary can be rebuilt.
