The LUNA SLM usees fast full digital addressing which assures high reliability and a compact driver unit. A certain gray level represents a defined average voltage across the LC cell. This voltage leads to a variable tilt of the LC molecules due to their electrical anisotropy. As LC molecules also show optical anisotropy this tilt changes the refractive index of the LC molecules (for incident polarization along the long display axis) which causes a modified optical path length within the LC cell. The addressed gray level is converted into a phase level.
The LUNA driver unit is equipped with an USB interface for changing the voltage vs. phase level distribution (gamma control) and dynamic range (voltage across the LC cell) in order to calibrate the SLM for different wavelengths.
