Abstract:
A photoacoustic wave measurement device includes: (a) a pulsed-light outputter that outputs a pulsed light; (b) an arrangement member disposed between a pulsed-light output end of the pulsed-light outputter and a measurement object, the arrangement member being adapted to allow the pulsed light to pass therethrough; and (c) a photoacoustic wave detector that receives a photoacoustic wave generated by the measurement object by the pulsed light and that converts the photoacoustic wave into an electric signal, the photoacoustic wave measurement device being adapted to receive the electric signal from a photoacoustic wave sensor in which the photoacoustic wave detector is farther from the measurement object than the pulsed-light output end. The photoacoustic wave measurement device further includes: an electric signal recording section that receives and records the electric signal from the photoacoustic wave sensor; a noise timing estimation section that estimates timing of occurrence of noise in the electric signal, from a thickness of the arrangement member; and a noise removal section that removes the electric signal at the timing estimated, from contents recorded by the electric signal recording section.
