Proper orthogonal decomposition (POD) is a widely used linear dimensionality reduction technique, but it often fails to capture critical features in complex nonlinear flows. In contrast, clustering methods are effective for nonlinear feature extraction, yet their application in dimensionality reduct...

Intense Poisson noise drastically degrades image quality when only a few or when a single photon hits each pixel. Multiaperture systems are able to provide multiple images of the same scene, which are acquired simultaneously. After registration and cropping, the partial scene information contained i...

A subwavelength gratings (SWG) assisted directional coupler (DC) is proposed to work as beam splitter (BS) for 850 nm chip-based optical coherence tomography (OCT). The bandwidth of the SWG assisted DC is maximized to 110 nm by selecting appropriate SWG geometries including its duty cycle and period...
