Title:
HOLOGRAPHY DEVICE AND CELL EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/215499
Kind Code:
A1
Abstract:
A holography device 10 has an optical system 200 that forms an interference image resulting from interference between objective light L1 and reference light L2. The optical system 200 includes: a phase element 30 disposed on an optical path for the objective light or the reference light; and a rotational mechanism 31 that causes the phase element 30 to rotate such that the optical axis of the objective light L1 or reference light L2 serves as the axis of rotation. The holography device 10 includes an image-capture unit 40 that captures the interference image; and a control unit 50 that derives an evaluation value for the interference image captured by the image-capture unit 40, and controls the rotation position of the rotational mechanism 31 on the basis of the evaluation value.
