Title: The Innovations of Andreas Hugi
Introduction
Andreas Hugi is a prominent inventor based in Zurich, Switzerland. He has made significant contributions to the field of spectroscopy, particularly through his innovative work on dual-comb spectrometers. With a total of 6 patents to his name, Hugi's inventions have advanced the capabilities of optical measurement technologies.
Latest Patents
One of Hugi's latest patents involves dual-comb spectroscopy. This invention comprises a dual-comb spectrometer that utilizes two lasers outputting respective frequency combs. These combs have a frequency offset between their intermode beat frequencies. In this setup, one laser acts as a master while the other serves as a follower. The master laser is driven with a nominal DC drive signal, but its current oscillates with an AC component that follows the beating of the intermode comb lines. This AC component is tapped off and mixed with a reference frequency to create the necessary frequency offset. The mixed signal is then supplied to the follower laser, ensuring that the frequency combs are phase-locked relative to each other. This innovative approach stabilizes the electrical signals obtained by multi-heterodyning the two optical signals.
