Phase ripple of spatial light modulators
Phase ripple is quantified by measuring the variation in intensity of the 1st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM. Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with high refresh rates (1400 Hz). The 1024 x 1024 SLM is good for applications requiring high speed. Rapid and programmable shaping of light fields is central to modern microscopy [1–3], display technologies, optical communications and sensing [4–6], quantum engineering [7–14], and quan-tum information processing [15–24].
