Abstract
A source light beam is split into an illumination beam and a highlight beam. The highlight beam can be controllably shaped into a shaped highlight beam based on a brightness analysis of an image to output. The illumination beam and the shaped highlight beam are combined and provided to an imaging device that generates the image using the combined beam. An array of reflectors, such as a MEMS mirror device, can be used in conjunction with a stacked rod array to generate the shaped highlight beam. The illumination beam and the shaped highlight beam can be combined using offset lenses or a polarizing beam splitter.
