Recent advances in high-contrast exoplanet imaging instrumentation have introduced the concept of adaptive coronagraphy. For example, liquid-crystal-on-silicon spatial light modulators (SLMs) can be used as programmable phase masks or digital micro-mirror devices as configurable pupil apodizers. Adaptive coronagraphy o...

The world’s first adaptive stellar coronagraph, the Programmable Liquid-crystal Active Coronagraphic Imager for the 4-m DAG telescope (PLACID) uses a spatial light modulator operating from H- to Ks-band to dynamically adjust the focal-plane phase mask entirely in software. Positioned between the TROIA XAO system and th...

Spatial Light Modulators (SLMs) are numerically programmable optical components that modulate the phase of light. We present digital holographic microscope (DHM) metrology results for the calibration of two classical liquid-crystal on-silicon (LCOS) VIS-633 nm SLMs: Meadowlark P1920 and Holoeye ERIS-NIR-153. For both d...
