Optical Power Spectrum Analysis of Display Imagery.

Abstract

This report describes the approach, procedures and results of a series of studies to examine the use of a simple, rapid measurement technique for the quantitative evaluation of display imagery. This technique, diffraction pattern sampling, provides an estimate of the image optical power spectrum. The resulting values are used to calculate the image information density for CRT imagery under various levels of display operating parameters. The resulting information density values are compared with observer target recognition performance under the same display conditions. The report considers the effectiveness, characteristics and limitations of the diffraction pattern sampling technique. (Author)
