THICKNESS-INFORMATION ACQUISITION APPARATUS, THICKNESS-INFORMATION ACQUISITION METHOD, THICKNESS-INFORMATION ACQUISITION PROGRAM AND MICROSCOPE

摘要

A thickness-information acquisition apparatus includes: an image acquisition section configured to acquire a phase-difference image of a sample; a correlation-distribution computation section configured to compute a correlation distribution of an image in the phase-difference image with respect to pixels of another image in the phase-difference image; and a thickness-information acquisition section configured to acquire information on the thickness of the sample in accordance with the correlation distribution.
