Description

本発明の装置は、光源から発生した光を被検体に導く導光手段と、照射された光を吸収した前記被検体が発生する弾性波を検出する検出手段と、前記検出手段と、前記導光手段の少なくとも一部と、を収納するプローブ筐体と、を有する装置であって、前記プローブ筐体の少なくとも一部が部材で覆われた状態で、前記プローブ筐体に収納された前記導光手段の前記少なくとも一部から射出される光を検査することを特徴とする。 Equipment of the present invention includes: a light guiding means for guiding the light generated from the light source to the object, and detecting means that detect the acoustic waves the subject occurs that absorbs the irradiation light, and the detection means the at least a portion of the light guide means, and a probe housing accommodating the, a equipment that have a, in a state where at least a portion of the probe housing is covered by a member, said probe housing The light emitted from the at least part of the light guiding means accommodated in the light is inspected .

Claims

A light guiding means for guiding light generated from the light source to the subject;
A detecting means that detect the acoustic waves the subject which has absorbed the irradiated light is generated,
Said detecting means, a equipment that Yusuke a probe housing for accommodating at least a portion, and the of the light guide means,
Wherein in a state where at least a portion of the probe housing is covered by a member, at least a portion it wherein examining the light emitted from the equipment of the light guide means housed in the probe housing .

Covering at least a portion member, equipment according to claim 1, characterized in that it is detachably attached to the probe housing of the probe housing.

Member covering at least a portion of the probe housing, equipment according to claim 1 or 2 characterized by having a member for checking the intensity of the light.

The member for inspecting the light intensity has a reference member whose Gruneisen parameter and absorption coefficient are known,
When inspecting the light intensity, the light intensity is inspected by irradiating the reference member with light emitted from the at least part of the light guide unit housed in the probe housing. equipment according to claim 3, characterized in.
