This course will introduce students to the interdisciplinary field of hyperspectral imaging. Hyperspectral imaging (HSI) is a broad term encompassing spatially resolved spectral data obtained through a variety of modalities (e.g. Raman scattering, Fourier transform infrared microscopy, fluorescence, visible or near-infrared). It goes beyond the capabilities of conventional imaging and spectroscopy by obtaining spatially resolved spectra from objects at spatial resolutions varying from the level of single cells up to macroscopic objects (e.g. foods).

In this module, students will learn how to become critically aware of the basic principles, practice and applications of hyperspectral imaging. Particular focus is given to the fundamentals of hyperspectral image acquisition and analysis. Standard approaches and configurations for obtaining hyperspectral imaging data, spatial and spectral pre-processing methods and methods of data selection will be explored and the underlying theory will be illuminated through the use of real world examples. The extension of traditional multivariate data analysis tools to hyperspectral data will be probed and students will apply these basic principles to examine established and emerging applications of hyperspectral imaging.

Students will participate in lectures, through group work in tutorials and laboratory work, where they will select and evaluate an application in hyperspectral imaging. Participants will also be provided with hyperspectral data to explore using chemometric tools developed in MATLAB.
