We’ve long been using the term ''fingerprint'' to describe the data produced in a single laser shot on a sample. A graph of the data indicates the intensity (amplitude of energy) at each wavelength on the spectrum detected by the spectrometer in our system. The term has proved to be somewhat awkward, because of other associations, so we’re making a change while public discussion of the technology is just beginning.
Materialytics will hereafter use the term ''spectrum'' for the data produced in a single laser shot on a sample.
The data from a single shot constitute the spectrum. All the spectra collected from a sample constitute its Quantagenetics® Sequence. Sequences of samples that have something in common (e.g. geographical origin) constitute a Quantagenetics Signature.
For our use, ''spectrum'' is a better fit.
