- W1993996370 abstract "An automatic and computerized system, using stepping motor controlling and photometric sensing techniques, is specifically designed to measure photometric and chromatic characteristics of projection TV. The head of luxmeter in this system is set on a translation stage whose position is constrained along two orthogonal linear rails. The x-y translation stage is controlled by two stepping motors with a personal computer. It can take two dimensional scan at any position on projection screen. Byu scanning the screen, the measurements of total lumen, uniformity, efficiency, color coordinate, color temperature, color uniformity, and contrast for projection TV can be wholly done spontaneously. The controlling and analyzing software of these measurements were also well developed and described. In this paper, the experimental set up and results were shown. The methods and standards of these measurements were also discussed." @default.
