Active Fourier Spectroscopy: From fixed sampling protocols to adaptive measurement
J. Schroeder, J. Schröder, S. Howard +5
Fourier-transform spectroscopy (FTS) is based on the Nyquist-Shannon theorem, which dictates a strict sampling protocol for the measurement of continuous signals. Here we introduce…
