“…More than forty years ago, enthusiasm for large-screen display and optical data processing in parallel architectures promoted invention and development of spatial light modulators (SLMs). [1][2][3][4] Such devices can manipulate light by modulating its amplitude, phase or polarization in dimensions of space and time as demanded. 5,6 Nowadays, the SLMs already make its quiet, yet steady entrance into our daily lives and cutting edge researches, ranging from portable displays, virtual reality, light detection and ranging, and adaptive optics, etc.…”
