Abstract
A mapping-measurement apparatus includes a light illumination unit, a photodetector for detecting, through an aperture, reflection light or transmission light from a sample, and adjustable scanning mirrors on the illumination and detection sides of the sample, each mirror having two independent rotational axes about which they can be independently rotated by a controller. The aperture restricts light incident on the photodetector from a predetermined portion of the sample surface.
