The digital control of an experiment to size particles using a laser
Abstract
Efforts to automate an experiment for sizing particles using a laser is described. The objective of the experiment was to rotate a photomultiplier detector at various angles and to record data associated with how light interacted with a particle. The light source was a laser which was fixed in space. The design consisted of a step motor with a fabricated electromechanical system to rotate the photomultiplier. The use of an 8080 microprocessor based microcomputer to control the step motor and to log data is described.
