Abstract

An image pickup apparatus includes a signal acquisition unit and a rotation unit. The signal acquisition unit includes an illumination unit including a light source and configured to irradiate a sample with a light beam, a photodetector including a plurality of light-receiving portions two-dimensionally arranged, and a detection optical system configured to guide light having been irradiated from the illumination unit to the sample and passed through the sample, to the photodetector. The rotation unit rotates the sample and the signal acquisition unit relative to each other, about a first axis intersecting an optical axis of the detection optical system in the sample. The illumination unit irradiates the sample with light beams at two or more incident angles in a plane including the optical axis and the first axis.
