High Joint Spectral-Spatial Resolution Imaging via Nanostructured Random Broadband Filtering

It is a challenge to acquire a snapshot image of very high resolutions in both spectral and spatial domain via a single short exposure. In this setting one cannot trade time for spectral resolution, such as via spectral bands scanning. Cameras of color filter arrays (CFA) (e.g., the Bayer mosaic) cannot obtain high spectral resolution. To overcome these difficulties, we propose a new multispectral imaging system that makes random linear …
