Introduction
1. Introduction
1.1 Description
The santec spatial light modulator (SLM) is based on reflective liquid crystal on silicon
(LCOS) microdisplay technology. The SLM has an active matrix display with 1920 x
1200 resolution (WUXGA) and a 0.63 diagonal which enables the SLM to modulate
optical phases freely and generate arbitral 2D phase patterns (gratings, phase mask,
holograms, etc.) on a LCOS pixel-by-pixel basis. The phase response of SLM is
adjusted even for different wavelengths (450 to 1600 nm) automatically using proprietary
GUI software with built-in adjustable gamma control. The signal is addressed via a
standard DVI (Digital Visual Interface) signal e.g. by a PC’s graphics.
The SLMs are characterized by ultra-low phase fluctuation from high drive frequency over
1kHz and 10bit high resolution addressing. These abilities are suitable for various
applications including laser material processing, optical switching devices, wavefront
correction and pulse shaping.
