Fast super-resolution of hyperspectral 2d raman data

Abstract

Raman images are restored using interior point least squares (IPLS). Bounding hyperplane-based hyperspectral unmixing reduces the dimensionality of the data cube, substantially decreasing computation time. IPLS is then independently applied to all resulting map images. The proposed method is first validated on simulated data and then being applied to real Raman spectroscopic data. The results allow for better physical characterisation of the sample and the spatial resolution is enhanced from 400nm to better than 50nm.
