Abstract: Laser light sources used in digital projectors have the potential to increase quality for several image parameters, including high brightness, dynamic range, and color space. This paper discusses advantages of laser illumination for digital projection, as well as considerations for the design of future cinema parameters such as luminance standards, high dynamic range projection, and a wider color space, including the practicality of the color space of The International Telecommunications Union Radiocommunication Sector Recommendation ITU-R BT.2020 (Rec. 2020)<sup>1</sup> as a projection gamut. Practical concerns and limits of lasers are examined in the context of near-term implementations, and suggestions for future theater and projector design are discussed.

bio
Jim Houston is principal of Starwatcher Digital, consulting in digital imaging systems for motion pictures and television production, and is active in standards development for digital cinema, high dynamic range video, and metadata workflows. Previously, he was vice president of technology and engineering for Sony Pictures, where he designed and built its 4K post-production facility and deployed the Sony production backbone digital asset management system. Houston also volunteers as co-chair of the Academy Color Encoding System project for the Academy of Motion Pictures Arts and Sciences; a color management framework for HDR and wide-color gamut imaging, which was recently released for industry use.
William Beck
bio
Bill Beck is a photonics visionary with diverse start-up, general management, and technology marketing experience. He has been central to the development and application of laser illumination systems for digital cinema and other performance projection applications. Beck supports Barco as “The Laser Guy,” to commercialize and further develop laser projection for cinema and other applications in key Barco markets. Beck co-founded and represents Barco in the Laser Illuminated Projection Association (LIPA) where he served as past chairman. He frequently writes and presents on the subjects of lasers, laser projection, and fiber optics. Before joining Barco, Beck founded BTM Consulting, LLC, providing expertise in the laser projection space. Before that, he was founding chief executive officer of Laser Light Engines, a pioneer in the early development of RGB laser illumination for performance projection. Beck earned a B.A. from Dartmouth College and an M.B.A. from Rensselaer Polytechnic Institute. He is a member of SMPTE, LIPA, Inter-Society Digital Cinema Forum, European Digital Cinema Forum, the Optical Society, and NEFC.
