Abstract
We present a projection optical system incoporating a dynamic optical element and we outline some of its potentional applications for digital projections. We describe experiments undertaken to validate a variety of these applications, in particular: change of focus without mechanical motion of the focus group; correction of chromatic aberration; and correction of a variety of other aberrations. We conclude that dynamic optical element can be used to improve the quality of image achieved from a very simple digital projection optical system.
