20.4: Image Quality in Flat Projection Wedges

We report a flat projection display with a 20 mm thick screen, 14″ diagonal, brightness of 5000 cdm−2 and resolution of ∼600×800 pixels. The display is made of off-the-shelf PMMA and uses an unmodified video projector with only keystone predistortion. Optical modeling predicts XGA resolution on a 20 mm thick screen with a diagonal of 50″, brightness of 500 cdm−2 and contrast the same as for conventional projection.
