Evaluation of the Barco 9200 LC LCD Light-Valve Projector

Abstract

The present study evaluates a production unit of the Barco 9200 LC high-resolution color LCD light-valve projector and Stewart AMl2O SN 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 on/off 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 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.
