"double-layer liquid crystal processes information using light propagation's laws, not digital conversion, switching between twisted/ non-twisted states (synthetic phase modulation)... high-speed, low-power, integrates 8 image processing functions into single architecture: single /dual-channel bright-field imaging, vortex filtering, 1D edge enhancement, vertex recognition, resolution-tunable edge extraction based on photonic spin Hall effect... front-end processor for autonomous driving, biomedical imaging"
