Increased Efficiency through Undersampling in Fourier Transform Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

We present the use of undersampling with a narrow band FTS operating in the step-and-integrate mode. Spectra can be unambiguously retrieved from interferograms sampled at less than the DC band-limited Nyquist sampling interval.
