Spatial-Spectral Trade-offs in Metasurface-Based Snapshot Hyperspectral Imaging

Snapshot hyperspectral imaging maps a spatial--spectral datacube onto a two-dimensional detector, with recoverability depending on the datacube sampling regime, the scene prior, and the optical encoding. We study this co-dependence with algorithmic recovery and optical design optimization in a differentiable metasurfac...
