Best digital noise reduction in optical spectra measurement

by Eggman   Last Updated July 31, 2018 07:25 AM

I am using an optical spectrometer to measure the reflectance of some surfaces; the output is essentially a set of photodiodes' signals: for each PD I have a discrete time signal every T.

What would be the best digital way to reduce the noise of the measurement? The simplest solution seems to be averaging, which enhances the SNR of sqrt(N) (under hypothesis of white uncorrelated noise), but is that the best that can be done?
