Two active spatial light modulators have been developed by Holoeye Photonics AG. The LC-R 768 and 720 modulate coherent or incoherent light spatially in amplitude and phase. Both have a reflective liquid-crystal-on-silicon microdisplay with WXGA 1280 × 768-pixel resolution and a fill factor of 92%. Pixel pitch for the LC-R 768 is 12 µm and for the LC-R 720 is 20 µm. Frame rates are 60 and 180 Hz, respectively. With an intensity ratio of 4000:1 using a 633-nm coherent light source, the LC-R 768 is suitable for use in imaging and projection applications. The LC-R 720’s response time of <3 ms and its frame rate make it suitable for high-speed applications.
