Abstract
A probe includes a transmitting and receiving unit in which an ultrasonic wave transmitting and receiving unit and a light transmitting and receiving unit are arranged. The ultrasonic wave transmitting and receiving unit and the light transmitting and receiving unit are arranged along an axial direction. A distance L [mm] between a position of the ultrasonic wave transmitting and receiving unit in the axial direction and a position of the light transmitting and receiving unit in the axial direction, and the angular difference θ [degrees] between a transmit direction of an ultrasonic wave of the ultrasonic wave transmitting and receiving unit and a transmit direction of light of the light transmitting and receiving unit satisfy a relationship of L=V/ω×θ/360 when having a rotary velocity ω [r/s] of the transmitting and receiving unit 221 and a movement velocity V [mm/s] of the transmitting and receiving unit 221 in the axial direction.
