Abstract
A holography apparatus 10 includes an optical system 200 that forms an interference image due to interference between object light L1 and reference light L2. The optical system 200 includes a retarder 30 that is disposed on an optical path of the object light or the reference light, and a rotation mechanism 31 that rotates the retarder 30 with an optical axis of the object light L1 or the reference light L2 as a rotation axis. The holography apparatus 10 includes an imaging unit 40 that captures the interference image, a control unit 50 that derives an evaluation value for the interference image captured by the imaging unit 40 and controls a rotational position of the rotation mechanism 31 based on the evaluation value.
Claims8
A holography apparatus comprising:
- an optical system that forms an interference image due to interference between object light and reference light, the optical system including a retarder that is disposed on an optical path of the object light or the reference light and a rotation mechanism that rotates the retarder with an optical axis of the object light or the reference light as a rotation axis;
- an imaging unit that captures the interference image;
- and
- a control unit configured to derive an evaluation value for the interference image captured by the imaging unit, and control a rotational position of the rotation mechanism based on the evaluation value.
