The X10468 series devices are a reflective type of pure phase Spatial Light Modulators (SLMs), based on Liquid Crystal on Silicon (LCOS) technology in which liquid crystal (LC) is controlled by a direct and accurate voltage, and can modulate a wavefront of light beam. The LCOS-SLMs are carefully designed to achieve high light utilization efficiency from various points of view, such as reflectivity, aperture ratio and diffraction noise due to the pixel structure.
The X10468 series can be controlled via a PC using the Digital Video Interface (DVI), which is a standard interface for computer displays. The distortions in the LCOS chip, such as wavefront distortion and nonlinear response of the LC, are efficiently compensated by the controller.
Easy computer control, precise and linear phase modulation characteristics can be accomplished with the X10468 series. They can also provide high diffraction efficiency and high light utilization efficiency.
The LCOS chip has a parallel-aligned nematic liquid crystal layer to modulate light. It only changes the phase of light without any change of intensity and rotation of polarization state. Phase modulation is changed according to the alignment of the LC. The LC alignment is controlled, pixel by pixel, using a CMOS backplane and a DVI signal via a PC.
