Chemical imaging spectroscopy is an exciting new analytical advance that answers commonly asked questions such as what chemical species are in a sample, how much of each is present, and most importantly, where are they located? Through the fusion of traditional infrared spectroscopy with powerful microscopic and macroscopic imaging capabilities, chemical imaging spectroscopy answers all these questions simultaneously, in a single rapid measurement.

At the end of the last column we promised that this time we would show how matrix algebra can be used for real computational tasks. The chosen task is Fourier transformation (FT) of a near infrared (NIR) spectrum. Those who know Tony Davies will not be surprised at this choice of subject but in the third lesson the reason for wanting to do the obvious will become apparent.
