Titel
Design and realization of an ultra-slim array projector
Abstract
State of the art projectors with a single aperture optical layout always require a trade-off between system volume and projected flux caused by étendue limitation. The presented 'array projection' technology overcomes this constraint of traditional concepts by an optical multi-aperture setup using arrayed microlenses as projection objectives. Furthermore, the presented multi¬channel approach enables for a unique extension of depth of focus, which ensures a brilliant image contrast even for extreme screen geometries without decreasing the system transmission. We present the design and realization of a first prototype for fixed projection patterns and show results of simulations regarding to depth of focus extension.
