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

A sound pressure metrology instrument determines sound pressure from index of refraction and includes: a light source that produces source light; the optical cavity that: receives an acoustic field from the sound source; receives the source light from the light source; produces acoustic-modified
Disclosed is a direct digital chirp synthesizer for generating a chirped optical frequency comb that includes: a direct digital synthesizer that receives a repetition frequency signal from a delay generator, receives a clock frequency from a frequency converter, produces a radiofrequency chirp

We have developed and demonstrated a new method to calibrate laser Doppler vibrometers (LDVs). The method uses two acousto-optic modulators to frequency shift the light from the LDV under test by a known quantity to create a synthetic velocity shift that is traceable to a time and frequency
