Abstract: A transparent-ultrasonic-sensor-based optical-ultrasonic integrated endoscopic probe according to one embodiment of the present disclosure may comprise: an optical fiber laser unit for emitting light; a transparent ultrasonic sensor, which is arranged between an object to be measured and the optical fiber laser unit to transmit, therethrough, the light emitted from the optical fiber laser unit, coaxially aligned with the light emitted from the optical fiber laser unit, radiating ultrasonic waves at the object, and receiving reflected ultrasonic waves; and a camera for acquiring an image of the object through the transparent ultrasonic sensor.
