Paper Abstract

A new illumination concept for fringe projection will be presented. Up to now fringe projection systems were based on reflective and/or transmissive microdisplays like digital micromirror devices (DMDs), nematic liquid crystals displays (LCDs) or liquid crystal on silicon displays (LCOS). But the size of the light source and of the illumination optic is a strong limitation for the miniaturization of the sensor system itself or for the integration in other illumination setups. Here we propose to use a high-brightness OLED-display (organic light-emitting diode) as active element for fringe pattern generation, giving the possibility to realize compact projection units.
