Episode Synopsis "ECE 616 Student Presentation: Dual-Comb Spectroscopy"

Dual comb spectroscopy is introduced, a technique that is basedon the beating of two frequency combs. A sample is first interrogated bythe combs before they are beat together via photodiode which down convertsthe signal from the optical to RF domain where it can be processed with electronics. A overview of the concept is given as well as a brief look intocurrent achievements and limitations.
