Dual purpose passive screen for simultaneous display and imaging

Abstract

Advanced imaging and display techniques are widely explored for realistic content capture and visualization but cannot fully follow the miniaturization and mobility trends in technology. Wide field-of-view displays require large surfaces and image capture requires separate installation of cameras having separate footprints and perspective views. Here we propose a novel, portable dual purpose passive screen that can simultaneously facilitate display and imaging with unprecedented features and performance. The optical design of the screen is presented. A prototype of the dual-purpose screen paired with a camera and a low power mobile projector is demonstrated. The developed screen has size of 28x21cm(2) to facilitate capture of eye contacted perspective view and displays high-quality images with high-brightness (>100cd/m(2)) using only 15 lumen pico projector.
