What are reflectance spectra and synchronous spectra?

Click For Summary
SUMMARY

Reflectance spectra and synchronous fluorescence spectra are essential tools in studying plant and animal tissues. Reflectance spectra provide intensity versus wavelength data, revealing information about chromatin and hemoglobin concentrations. In contrast, synchronous fluorescence spectra involve scanning measurements that yield fluorescence data based on position. Both techniques are crucial for biological and chemical analyses, offering insights into the composition and characteristics of various materials.

Please be sure to read our guidelines; I notice that you've posted this same in another section - I'll be locking that.
 
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.
