A compact multicolor beam illuminator and a compact multicolor beam expander are presented.
The illuminator performs the dual task of demultiplexing a narrow red-green-blue (RGB)
input beam into three separate beams, each of a different color, and expanding them
to yield three separate magnified plane waves. The beam expander expands a narrow
RGB input beam into a single magnified RGB plane wave. The design and recording procedures,
along with experimental results for abeam illuminator and a beam expander with a magnification
of similar to3, are presented. (C) 2002 Optical Society of America.
