Abstract Ultrafast dynamic vision remains a major challenge for autonomous systems like drones, particularly considering their strict power and computational constraints. Here, we present an artificial spherical compound eye (ASCE) that enables nanosecond-scale, event-driven motion detection across a panoramic field of view (294°). Each pixel is self-powered and responds exclusively to dynamic light changes, enabling real-time sensing with minimal processing.

Abstract Sensitive, label-free detection of biomarkers is critical for clinical diagnostics. However, conventional nanophotonic biosensors typically remain confined to either the real or imaginary components of the refractive index. This isolation results in weak signal responses, limited operational stability and high instrumental complexity. Here we introduce a Q-modulated refractometric sensing mechanism that operates in the complex-variable domain.
