able to make their scanners so small is
that their design philosophy has been to
perform many of the scanning functions
using software rather than hardware.
Another significant contributor to
the small size is that they use a single
two-axis MEMS mirror instead of one
for each axis.
The optical input coupler is part of
the waveguide. The coupler is a pattern
of microstructure gratings on the surface
that allow the light to enter. There
4
are similar structures on the output
side, where the light leaves the waveguide.
Optical
System
The optical system consists of a waveguide
with input and output couplers.
The image output from the scanner is
directly coupled into the waveguide,
which is a two-dimensional glass structure.
It takes the very small input image
- only a couple of millimeters wide -
