The invention discloses a real-time multi-mode photoacoustic
human eye imaging
system and an imaging method thereof. The imaging
system comprises a
laser device, a front
optical path, a reflecting mirror, a focusing lens, a light-transmitting
acoustic reflection device, a
scanning mirror, a water trough, an ultrasonic probe, an ultrasonic
transmitter-
receiver set, an
amplifier and a computer. A light-transmitting
acoustic reflection film and the
scanning mirror are placed in the water trough. The imaging
system has a photoacoustic imaging mode and an
ultrasonic imaging mode. Mechanical scanning is replaced through the
scanning mirror, imaging time is greatly shortened, and pain of a patient is relieved. Meanwhile, due to the optical and ultrasonic
confocal design, an existing pure
optical focusing imaging mode or an existing pure ultrasonic focusing imaging mode is changed, sensitivity is improved on the basis that the
optical resolution is achieved, and full-eye imaging from the front of the eye to the bottom of the eye can be carried out. Due to dual-
wavelength use, the limitation that imaging is only carried out on the eye
vascular structure at present is broken through,
functional imaging of the degree of blood
oxygen saturation can be carried out, and
early detection of a part of eye diseases is facilitated.
