Abstract

Phase retrieval methods are used to recover Raman spectra from multiplex and broadband CARS signals. Two methods are in widespread use, one based on maximum entropy (MEM), and one based on a modified time-domain Kramers-Kronig (TDKK) method. Here we compare these methods with respect to their ability to faithfully and robustly recover Raman spectra from CARS spectra simulated to reproduce a range of scenarios expected for real experimental data. We find that TDKK and MEM approaches perform in functionally equivalent ways, having only minor differences between them.
