Abstract
The utility model discloses an optical acousto-optic sheet bimodal imaging system, and relates to the technical field of microscopic imaging. Continuous laser; the pulse laser and the continuous laser irradiate on the dichroscope to generate reflected pulse laser and transmitted continuous laser respectively, and the reflected pulse laser and the transmitted continuous laser are combined to form a laser beam; the galvanometer reflects the laser beam to form scanning laser; the scanning objective lens transmits the scanning laser to form a scanning light beam, and the sample generates ultrasonic waves and fluorescent light under excitation of the reflected pulse laser and the transmitted continuous laser; the ultrasonic detector is used for collecting ultrasonic waves and forming corresponding ultrasonic signals; and the camera is used for collecting fluorescence to form a corresponding fluorescence signal. In the application, the pulse laser for exciting the ultrasonic wave and the continuous laser for exciting the fluorescence are highly overlapped on the light path, so that the problem of huge system size caused by independent design of the light path is avoided.
