    Abstract: A microscope apparatus includes SLMs each having a modulation plane, an objective lens disposed on an optical path between the modulation plane and an object, and a computer for controlling the SLMs on the basis of a modulation pattern including a correction pattern for correcting aberration caused by a refractive index interface of the object. The computer determines a position of the correction pattern in the modulation pattern on the basis of inclination information of the refractive index interface with respect to a plane perpendicular to an optical axis of the objective lens.

    Abstract: An image acquisition device includes a spatial light modulator modulating irradiation light, a control unit controlling a modulating pattern so that first and second light converging points are formed in an observation object, a light converging optical system converging the irradiation light, a scanning unit scanning positions of the first and second light converging points in the observation object in a scanning direction intersecting an optical axis of the light converging optical system, and a photodetector detecting first observation light generated from the first light converging point and second observation light generated from the second light converging point. The photodetector has a first detection area for detecting the first observation light and a second detection area for detecting the second observation light. The positions of the first and second light converging points are different from each other in a direction of the optical axis.

    Abstract: A fluorescence receiving apparatus comprises an excitation light source, a spatial light modulator of a phase modulation type for phase-modulating excitation light to obtain phase-modulated light, a focusing optical system configured to focus the phase-modulated light to a specimen, a specimen stage for supporting the specimen, a fluorescence receiver for receiving fluorescence generated by focus of the phase-modulated light to the specimen, a control unit for displaying a first CGH on the spatial light modulator, and a correction unit for correcting the first CGH. The correction unit comprises a receiver-specific sensitivity information storage preliminarily acquiring and storing sensitivity information per reception position specific to the fluorescence receiver, and a second hologram generator for correcting the first CGH, based on intensities of the fluorescence and the sensitivity information, to generate a second CGH. The control unit displays the second CGH on the spatial light modulator.
