Abstract

A closed loop scanning and positioning system for finding and positioning white blood cells includes a multifaceted rotating mirror, an optical system, two photoelectric sensors, two light sources and a logic circuit. The logic circuit produces signals which are used to drive a microscope stage in x and y directions to cause the blood cell to be positioned within a small aperture.
