Analyte-information acquisition apparatus

摘要

To improve the safety of a photoacoustic apparatus by preventing illumination light from being freely emitted. A photoacoustic apparatus includes a position sensor that measures the orientation and/or position of an illumination-light emission end and a control unit that controls light emission from a light source depending on the output of the position sensor.

1. An apparatus comprising:
a light emitting unit including an emitting portion that emits light to be applied to an analyte; a probe configured to receive photoacoustic waves that the analyte generates when receiving the light emitted from the light emitting unit and to output an electrical signal; a detecting unit configured to detect information concerning speed of movement of the emitting portion; and a control unit configured to control the light emitting unit on the basis of a detection result of the detecting unit, wherein the control unit controls the light emitting unit in such a manner that the emitting portion does not emit light in a case where it is determined that the speed of movement of the emitting portion does not correspond to a predetermined value or less, the predetermined value being not zero, on the basis of the detection result of the detecting unit.
