Claim of US Patent No. 9,439,267

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.
