flying spot microscope

A microscope that uses a flying spot scanner, directed through the eyepiece, as a light source to determine the features of a transparent specimen. The flying spot is modulated by the varying density of the specimen producing a light beam of changing intensity which is detected by a photoelectric cell. The photoelectric cell converts the light into corresponding electrical signals which are fed to a cathode-ray tube, resulting in a display of the specimen.
