Computer Control of Basic and Applied Experiments in Spark Emission Spectroscopy

Volume 36, Number 6 (Dec. 1982) Page 617-626

Mathews, Samuel E.; Ekimoff, David; Walters, John P.


A hardware system is described which provides for software-independent timing of events necessary for the smooth operation of an adjustable waveform spark source. Illustrative cases are given showing the extension of this system into a single-channel spectrometer and a complex schlieren photography experiment. Software outlines are also provided. The use of an optical coupler and a fiber optic are shown to improve system performance greatly in high radio frequency interference environments.
