2.2 Operating principle
The SLM is an optical intensity or phase modulator using LCOS display technology that
consists of a silicon-based reflective, active matrix CMOS driver which uses a nematic
liquid crystal. LCOS has several million 2-dimensional pixels separated by a few tenths
of a micron and can address pixel-by-pixel. Optical phase or intensity can be controlled
spatially by the voltage level applied to each pixel.
The SLM can be controlled via a PC using the DVI and USB interface. Easy control using
the attached optical phase (intensity) editor and graphical user interface (GUI),
wavelength independent precise and linear phase modulation with software built-in
gamma control can be accomplished.
