Abstract

BlackScreen rear-projection display screens, developed by Jenmar Visual Systems, are well suited for cockpit avionics applications primarily because they exhibit both high image resolution and high ambient light rejection. These characteristics combine to produce highly visible high-contrast images, even in very brightly lit viewing environments. On-screen optical noise commonly referred to as speckle and grain, can be a problem in these screens. This paper will describe the methods we have developed to measure speckle and grain. We will also show data from prototype screens that we have modified to reduce the magnitude of these artifacts.
