Overview: The goal of this NIST task included the characterization of the performance of the projection system intrinsically as well as within the environment in which it is used. Such measurements require the separation of the quality of the projector from the effects of the room. Publications: Luminous Flux Based upon Color Primaries: (NISTIR-6657 Projector RGB-Flux.pdf) -- This paper describes a method to measure the flux from a projector so that any extra color or white primary other than RGB is not involved. This flux, nicknamed color output, is suitable for projectors used for the display of imagery. Citation: E. F. Kelley, K. Lang, L. D. Silverstein, and M. H. Brill, "A Rational Methodology for Estimating the Luminous Flux Based upon Color Primaries from Digital Projection Displays," NISTIR 6657, 29 pp. , January 2009. NIST Stray Light Elimination Tube Prototype: (SLET_04.pdf) -- This paper describes the creation and use of the first SLET, how to make a portable darkroom using a SLET, and the use of a slit illuminance meter with a SLET. Citation: P. A. Boynton and E. F. Kelley, "NIST Stray Light Elimination Tube Prototype," NISTIR 6861, March 2002. Stray Light Compensation in Small Area Contrast Measurements of Projection Displays: (SLET_03.pdf) -- Grille contrast and resolution measurements are made and compared using (1) a line mask, (2) a slit illuminance meter with a SLET, and (3) an array camera with no veiling-glare corrections. Citation: P. A. Boynton and E. F. Kelley, "Stray Light Compensation in Small Area Contrast Measurements of Projection Displays," Projection Displays VIII, Proceedings of the SPIE, Vol. 4657, pp. 122-130 (January 2002). Compensation for Stray Light in Projection-Display Metrology: (SLET_02.pdf) --This paper adds to one immediately above by illustrating the use of a SLET with a portable darkroom to measure rear projection displays, by showing the mixing of colors from stray-light contamination, and by introducing some simplified modeling for front-projection displays. Citation: P. A. Boynton and E. F. Kelley, "Compensation for Stray Light in Projection-Display Metrology," 2001-SID International Symposium Digest of Technical Papers, Society for Information Display, Vol. 32, pp. 334-337, San Jose, CA, June 4-8, 2001. Light Measuring Device Diagnostics for the Photometric and Colorimetric Measurement of Flying-Spot Displays: (Flying_spot02.pdf) --This paper enhances the first paper above with more diagnostics and methods for characterizing light measurement devices and includes colorimetric results based upon narrow band sources. Citation: P. A. Boynton and E. F. Kelley, "Light Measuring Device Diagnostics for the Photometric and Colorimetric Measurement of Flying-Spot Displays," Proceedings of the SPIE V4295, Electronic Imaging Symposium, San Jose, CA, January 23, 2001. Diagnostics for Light Measuring Devices in Flying-Spot Display Measurements: (Flying_spot01.pdf) --This paper describes diagnostics for evaluating the use of light-measuring devices in measuring flying-spot displays. A bipartite comparator is used to investigate integration and saturation errors. Citation: P. A. Boynton and E. F. Kelley, "Diagnostics for Light Measuring Devices in Flying-Spot Display Measurements," Proceedings of the SPIE Vol. 3954, January 2000. Stray Light Elimination in Making Projection Display Measurements: (SLET.pdf) --This paper introduces the stray-light-elimination tube (SLET) to greatly reduce the effects of stray light in making measurements on the intrinsic properties of front-projection displays. The use of a projection mask is also described and compared with the use of the SLET. Citation: P. A. Boynton and E. F. Kelley, "Stray Light Elimination in Making Projection Display Measurements," International Society for Optical Engineering (SPIE) Electronic Imaging Conference, San Jose, CA, January 29, 1999.
