Abstract
A holography apparatusincludes an optical systemthat forms an interference image due to interference between object light Land reference light L. The optical systemincludes a retarderthat is disposed on an optical path of the object light or the reference light, and a rotation mechanismthat rotates the retarderwith an optical axis of the object light Lor the reference light Las a rotation axis. The holography apparatusincludes an imaging unitthat captures the interference image, a control unitthat derives an evaluation value for the interference image captured by the imaging unitand controls a rotational position of the rotation mechanismbased on the evaluation value.
