Abstract

A Tandem Scanning Microscope is disclosed using a modified Nipkow disk design. With this scanning system, scanning is performed using many apertures at once and using one disk for both image and illumination scanning. The apertures in the disk are in an annular pattern of spiral arms. Each aperture is located along a spiral arm at the end of a radius vector. Relative aperture locations are established in accordance with a mathematical relationship.
