Abstract

IN the flying spot microscope the specimen is scanned by a single spot and the resulting pictures displayed on a television monitor tube1. If the microscope specimen consists of a number of particles, and if the output of the microscope is taken directly to a high-speed counter, each particle will be crossed by the spot more than once, and the counter will register the total number of intercepts, giving a count greater than the number of particles in the field. In order to obtain a count equal to the number of particles in the field, the following development has been made.
