Abstract: A photoacoustic-ultrasonic (i.e. dual mode) endoscope includes: an optical fiber; a light diffuser configured to diffuse a laser beam delivered through the optical fiber to a target point of an object to be examined; and an array transducer through which the diffused laser beam passes and configured to generate ultrasonic waves or detect ultrasonic waves generated in the object to be examined.

Abstract: A photoacoustic and ultrasonic endoscope includes an optical fiber, a light diffuser configured to radially diffuse a laser beam transmitted through the optical fiber, and an array transducer having a cylindrical shape and surrounding the light diffuser, the array transducer being configured to transmit the diffused laser beam therethrough and to generate an ultrasonic wave or detect an ultrasonic wave generated by an object to be examined.
