An automated micrograph image size analyser

Abstract

An automated electro-optic image size analyser capable of rapid data collection is described. The device is especially suited to the determination of colloidal particle size distributions and grain or magnetic domain size analysis from electron or optical micrographs. The interfacing of the analyser, which is described, requires two input/output lines and a logic zero to an 8-bit parallel port of a microcomputer as well as two ADC channels. The apparatus is thus not fundamentally specific to any single type of microcomputer.
