Abstract

We perform numerical study of Compressive Multi-heterodyne Optical Spectroscopy [CMOS], which is based on multiple heterodyne measurements using a dynamically encoded frequency comb. Compressive sensing enables us to utilize sparsity in typical optical spectra of interest to reduce the number of heterodyne measurements. Numerical results are presented to demonstrate retrieval of coherent and incoherent sparse hypothetical Lorentzian spectra over a 42 nm-wide bandwidth, sampled every 100 MHz (∼0.2 pm), by using as few as 25% measurements.
