IMOS Diffractive Optical
Elements (DOEs)
DOEs are diffraction structures. They can be precisely
replicated in plastic. It almost doesn't matter where the
laser beam vertically shines through the DOE structure.
Light is diffracted by tiny micro- and nanostructures so
that it can project the desired complex pieces of
information.
DOE give the collimated light of a laser its direction and
shape. DOEs combine into one the functions of various
optical elements, and are just a few millimetres high.
This minimal space requirement is a decisive
advantage.
