Abstract:

This report describes the results of two studies designed to measure dynamic noise, photometrically, on a raster-scan display. One study evaluated spot microphotometry of a single raster line the other evaluated microdensitometric power spectral analysis of close-up photographs of raster lines. The spot microphotometry technique proved superior and very reliable, yielding results that are highly correlated with input noise spectra. Author
