Forth Dimension Displays (ForthDD; Fife, Scotland), which makes fast binary spatial light modulators (SLMs), and LightTrans (Jena, Germany), producer of VirtualLab Fusion optical-design and simulation software, are collaborating on an adaptation of LightTrans's VirtualLab Fusion software so that it can support high-speed binary phase modulators made by ForthDD. Based on ferroelectric liquid-crystal-on-silicon (FLCOS) technology, ForthDD's binary SLM has QXGA (2048 x 1536 pixel) resolution at speeds up to 4.5 kHz with a pixel pitch of 8.2 μm. The drive interface supports either video (using the DisplayPort standard) or a dedicated flash-memory-based interface calling off up to 1024 binary phase masks from the onboard memory and controlled using flexible trigger ports.
