Latest Patents

One of his latest patents is titled "Fast computational phase and timing correction for multiheterodyne spectroscopy." This invention discloses an all-digital phase and timing correction procedure for coherent averaging in dual-comb and multiheterodyne spectroscopy. The technique is applicable to any dual-comb spectroscopy setup and can account for large frequency and phase instabilities of the sources used. This results in a significant reduction of the noise pedestal and an increase in the signal-to-noise ratio (SNR) of the radio frequency (RF) beat notes. The computational efficiency of this technique allows it to be implemented as either a post-processing algorithm or in a real-time data acquisition and processing platform, without the need for additional optical elements. By utilizing this method, the performance of any comb- or comb-like-source-based DCS system can be enhanced in terms of SNR and the number of spectroscopically usable RF beat notes. The technique is compatible with a DC-centered RF spectrum, effectively doubling the number of beat notes within the detector bandwidth. It also enables coherent averaging over extended time-scales, increasing the sensitivity of absorption and dispersion DCS measurements.
