Serrodyne Frequency Shift Spectrometer and Serrodyne Frequency Shifting

NIST Inventors

Sean Bresler , John R. Lawall and Benjamin Reschovsky

Direct multiheterodyne or self-heterodyne frequency comb spectroscopy commonly relies upon the use of an acousto-optic modulator to provide a frequency shift of the resulting radiofrequency interferogram. We have shown that serrodyne modulation can provide this shift, resulting in a significant
