Claim:
1. An apparatus for receiving fluorescence generated from a specimen by focus of phase-modulated excitation light, comprising: light source configured to output an excitation light; a spatial light modulator of a phase modulation type configured to input the excitation light, modulate phase of the excitation light and output the phase-modulated light; a focusing optical system configured to input the phase-modulated light and focus the phase-modulated light to the specimen; a stage configured to support the specimen; a light detector configured to detect fluorescence generated by the phase-modulated light, via the focusing optical system; a controller configured to control the spatial light modulator so as to display a first hologram to modulate a phase of the excitation light at each of a plurality of two-dimensionally arrayed pixels, thereby focusing the phase-modulated light at a plurality of focusing positions of the specimen by the focusing optical system; and a correction unit configured to correct the first hologram based on intensities of the fluorescence at the focusing positions and sensitivity information per reception position specific to the light detector, to generate a second hologram and, wherein the controller controls the spatial light modulator so as to display the second hologram.
