Event-based Shack–Hartmann wavefront sensing using spiking neural networks

Event-based sensors offer high temporal resolution, high dynamic range and low latency, making them wellsuited for wavefront sensing under high-speed turbulence. Recent work has demonstrated the effectiveness of event-based Shack–Hartmann wavefront sensing; however, many current methods rely on conventional framebased...

Implicit Neural Speckle Denoising

This work introduces a training-free framework that combines a spatiotemporal implicit neural representation with an aperture-aware maximum-likelihood formulation to recover dynamic, speckle-free imagery directly from noisy observations, enabling adaptation to arbitrary pupil geometries without retraining.
