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.
