Abstract
A photoacoustic microscope includes an objective lens that irradiates a specimen with excitation light, a light scanning unit that deflects the excitation light to scan the specimen, an acoustic lens that converts a wavefront of a photoacoustic wave generated by the specimen due to irradiation with the excitation light, a photoacoustic wave detection unit that detects the photoacoustic wave from the acoustic lens, a drive unit that displaces at least one of the acoustic lens and the photoacoustic wave detection unit, and a control unit that controls the drive unit, in synchronization with scanning of the excitation light by the light scanning unit, so that the photoacoustic wave is incident on the photoacoustic wave detection unit perpendicularly.
