Abstract
A complex amplitude information measurement apparatus (10) according to the present invention includes pixel sensor groups for generating a difference from one pixel sensor group to another in the optical distance of object light traveling from a measurement object (100); a camera (15) provided with an image sensor for recording, with a single-shot exposure, the object light that has passed through or been reflected from the pixel sensor groups to obtain intensity information of the measurement object; and a computer (16) for computing, on the basis of the intensity information, phase information of the measurement object (100).
