Abstract
The present invention offers an alternative strategy for the correlation of interference information to chemical and/or physical properties of a sample. This strategy can be implemented in a method and a system, which offer substantial technical and commercial advantages over state of the art techniques based on interference spectroscopy. The method comprises 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 i. at least one transformation of the interferogram and/or a segment of the interferogram and/or an interferogram element with at least one function, ii. optionally repeating i) for another segment of the interferogram and/or interferogram element, wherein the transformation does not comprise a Fourier Transformation if i) is conducted only once, thereby obtaining at least one score, c. correlating said at least one score to the at least one chemical or physical property.
