Method and apparatus for visualizing phase object

Abstract

A visualization apparatus includes a light source, an illumination optical system configured to guide light from the light source to an observation target object, an image forming optical system configured to form an optical image of the observation target object on an image plane, an image pickup element arranged on the image plane, a calculation device configured to calculate a plurality of first electronic images of the observation target object obtained from the image pickup element to generate a second electronic image, and an oblique illumination control section configured to control an illumination direction of oblique illumination provided by the illumination optical system. The plurality of first electronic images include first electronic images of the observation target object illuminated from different illumination directions by the oblique illumination control section.
