Abstract

A method of producing a light beam for a display system includes generating a light beam having a transverse cross section that is elongate along a longitudinal axis, and moving a plurality of beam-modifying optical elements sequentially along a travel path that intersects the light beam with the light beam cross-section longitudinal axis oriented transverse to the travel path.
