Subsampling dual-comb spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a technique to compress spectral information in dual-comb spectroscopy that relies on subsampling of the electrical interferogram. It enables us to reduce the data sample rate by arbitrary factors directly in the sampling process or in post-processing of existing data. A demonstration code is provided.
