A reflection-mode photoacoustic endoscope includes a tube, a light source configured to emit a light pulse suitable for photoacoustic imaging, an ultrasonic transducer configured to detect a response signal, and a light and acoustic reflector rotatable relative to the tube.

Miniaturized photoacoustic imaging apparatus including a rotatable reflector

A reflection-mode photoacoustic endoscope includes a light source configured to emit a light pulse, a signal detection or transmission unit configured to detect or emit an ultrasonic pulse, and a rotatable reflector. The rotatable reflector is configured to reflect at least one of the light pulse and the ultrasonic pulse into a target area of an object, and reflect a response signal to the signal detection unit. The response signal is one of a photoacoustic wave generated by the object responsive to the light pulse and an ultrasonic pulse echo generated by the object responsive to the ultrasonic pulse.
