IMAGING WITH SHAPED HIGHLIGHT BEAM

摘要

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.

1. An imaging apparatus comprising:
a light source configured to emit a source light beam; a beam splitter positioned to split the source light beam into an illumination beam and a highlight beam; a highlight apparatus positioned in a path of the highlight beam and configured to controllably shape the highlight beam into a shaped highlight beam; an optical combiner positioned to combine the illumination beam and the shaped highlight beam; and an imaging device positioned to receive combined light from the optical combiner and configured generate an image using the combined light according to image data.
