Multi-channel Optical Vision Model
Ali Momeni, Guillaume Noetinger, Tim Tuuva +1
Spatial multiplexing is one of the natural strengths of optics, yet in optical neural networks, it is often used mainly as parallel throughput. Here, we show that spatial multiplex…

Tutorial: A practical guide to the alignment of defocused spatial light modulators for fast diffractive neural networks
Guillaume Noetinger, Tim Tuuva, Romain Fleury
The conjugation of multiple spatial light modulators (SLMs) enables the construction of optical diffractive neural networks (DNNs). To accelerate training, which is limited by the…

Super-resolved imaging based on spatiotemporal wavefront shaping
Guillaume Noetinger, Samuel Métais, Geoffroy Lerosey +3
A novel approach to improving the performances of confocal scanning imaging is proposed. We experimentally demonstrate its feasibility using acoustic waves. It relies on a new way…
