Hybrid-resolution spectral imaging

The acquisition of a high-resolution spectral image is difficult because it requires huge amount of data. In hybrid-resolution spectral imaging technique, two different image data are simultaneously captured; (1) spatially high-resolution with low spectral resolution and (2) low spatial resolution with high spectral resolution. From those two images, a spectral image with high-resolution in both spatial and spectral information is numerically reconstructed. It is suitable for compact and efficient spectral imaging device, and applied to real-time spectral video.
