    What are reflectance spectra and synchronous spectra? What are the difference and which information I can obtain from them ?

    I think this thread will fare better in Biology or Chemistry. As far as I'm aware, both reflectance as well as synchronous fluorescence spectra are used most commonly, to study plant and animal tissue.

    Reflectance spectra simply record the intensity vs. wavelength data (normalized with respect to the source) for the light reflected off some material. Typically, such spectra tell you things about chromatin or haemoglobin concentrations...but a biologist might be able to answer this better.

    I think synchronous spectra involve a scanning/rastering measurement that gives fluorescence data as a function of position. This is just a vague recollection, so I repeat that this thread might be better served if moved to Biology or Chemistry.
