Abstract
Provided is a determination method capable of non-destructively and simply determining a state of a sphere that is an aggregate of a plurality of cells. A phase difference image of a sphere that is an aggregate of a plurality of cells is generated from a hologram obtained by imaging the sphere, and a state of the sphere is determined on the basis of the phase difference image and a shape index value corresponding to a shape of the sphere.
Claims19
A determination method, comprising:
- generating a phase difference image of a sphere that is an aggregate of a plurality of cells from a hologram obtained by imaging the sphere, wherein the phase difference image is a phase difference image of the sphere at a slice position in which variation in a phase difference amount between a plurality of pixels constituting the phase difference image is the maximum among a plurality of phase difference images that are generable from the hologram;
- and
- determining a state of the sphere on the basis of the phase difference image and a shape index value corresponding to a shape of the sphere.
