Title:
光音響プローブ
Document Type and Number:
Japanese Patent JP7168097
Kind Code:
B2
Abstract:
A photoacoustic probe includes a light source that emits light, an acoustic sensor that is arranged such that an axial direction is in parallel to a depth direction of an object to be measured and detects a sound produced from the object to be measured, a propagation member that propagates the light from the light source to the object to be measured, and propagates the sound produced from the object to be measured by emission of the light from the light source to the acoustic sensor, a reflection member that is provided within the propagation member, reflects the light from the light source, and emits reflected light to the object to be measured in the axial direction of the acoustic sensor, and a sweep mechanism capable of changing a position at which the light from the light source enters the reflection member.
