The present study evaluates a production unit of the Electrohome 9501LC high- resolution color CRT projector and Stewart Studiotek 130 projection screen. Only photometric measurements were performed on this system. The primary emphasis of the measurements is the determination of the contrast modulation of the display for onoff grille patterns. In turn, the contrast modulation measurements provide an estimate of the number of resolvable pixels that are displayed on the projection screen. The number of resolvable pixels is typically less than the addressability of the display, which is the number of positions that are electronically addressed. We provide below a description of the display that was evaluated and the details of the setup procedures used to prepare the display for measurement. Section II presents the data and results of the photometric measurements. Section III completes the report with analyses of the measurements and final conclusions.
