Photoacoustic microscope and photoacoustic signal detection method

Abstract

A photoacoustic microscope includes: a light source which generates pulse light; a focusing optical system which focuses the pulse light emitted from the light source and irradiate a sample with the focused pulse light; a photoacoustic signal detection unit which detects an acoustic signal generated from the sample through irradiation of the pulse light; an image signal formation unit which forms an image signal of the sample based on the acoustic signal; an information unit having information representing a relation between intensity of the pulse light entering the sample and intensity of the acoustic signal generated from the sample; and a pulse light intensity changing unit which changes intensity of the pulse light from the light source based on the information.
