Title:
QUALITY EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/122076
Kind Code:
A1
Abstract:
This quality evaluation method includes: a step of radiating measuring light having a wavelength at least equal to 300 nm and at most equal to 2000 nm onto a cell cluster, and acquiring a plurality of items of light intensity information corresponding to each of a plurality of measuring positions in the cell cluster; a step of generating a feature quantity from variability in the plurality of items of acquired light intensity information; and a step of evaluating the quality of the cell cluster using the generated feature quantity as an index.
