Abstract:
1. A method for the determination of chemical or physical property of a sample or a component of a sample comprising the steps of: a. obtaining an interferogram and/or at least one interferogram element corresponding to a modulation of electromagnetic signal emitted from, transmitted onto or through, or having interacted with at least a part of the sample, b. performing where I is interferogram data, f is function, x is domain of interferogram, and i is index to discrete interferogram elements, wherein the transformation does not comprise a Fourier Transformation if i) is conducted only once, thereby obtaining at least one score as defined by where I is the interferogram data, f is the function, x is the domain of interferogram, and i is the index to discrete interferogram elements, and c. correlating said at least one score to the at least one chemical or physical property.
