Coherence Awareness in Diffractive Neural Networks
Laser &Photonics Reviews, EarlyView.It is demonstrated that spatial coherence significantly impacts all‐optical diffractive neural networks, unlike imaging systems. A general framework is proposed for training diffractive networks for any specified degree of spatial and temporal coherence. Coherence‐blind networks are further introduced, which are resilient to illumination changes. These

Bendable Fiber Lens for Minimally Invasive Endoscopy
Laser &Photonics Reviews, EarlyView.Translating ex vivo imaging to minimally invasive in vivo applications is of outstanding scientific and socioeconomic relevance. 3D imaging based on tiny lensless fiber endoscopes requires complex setups and computational schemes, so far. Bridging this gap, imaging through a unique optical fiber that mimics the functionality of a lens but is minimally ...
