A Light-based Testing System for Detecting Chemicals and Materials

NIST Inventors
Fabrizio Giorgetta , Esther Baumann , JD Deschenes and Ian Coddington
This invention introduces a dual comb spectroscopy system that enhances optical measurement accuracy. It uses two optical frequency combs to analyze light absorption and emission with high precision. The system improves data collection speed and reduces errors in spectral analysis. It is designed to
