Abstract

An image acquisition device includes a spatial light modulator modulating irradiation light, a control unit controlling a modulating pattern so that a plurality of light converging points are formed in an observation object, a light converging optical system converging the modulated irradiation light, a scanning unit scanning positions of the plurality of light converging points in the observation object in a scanning direction intersecting an optical axis of the light converging optical system, and a photodetector configured to detect a plurality of observation lights generated from the plurality of light converging points. The control unit sets a center spacing between adjacent light converging points on the basis of the positions of the plurality of light converging points in a direction of the optical axis.
