Spatial Light Modulator
A programmable optical device capable of modulating the phase, amplitude, or polarization of incident light at the pixel level. The most common type uses liquid-crystal technology, which allows a digital matrix to be written into an optical field in real time. Applications include optical computing, holographic display, and related photonic information-processing tasks.
Timeline (last 90 days)
The spatial light modulator (SLM) is the core component for achieving dynamic holographic displays, capable of controlling the amplitude or phase of light waves pixel by pixel.
The system uses a digital encoder to extract compact feature representations from video, then encodes the features as phase patterns via a spatial light modulator (SLM).
The system in this study uses a reprogrammable SLM rather than a fixed structure, which offers greater flexibility compared to D²NN, while retaining a digital control loop.
