Author(s)
Kyunghun Han, David Long, Sean Bresler, Junyeob Song, Yiliang Bao, Benjamin Reschovsky, Kartik Srinivasan, Jason J. Gorman, Vladimir Aksyuk, Thomas W. LeBrun
Sensing platforms based upon photonic integrated circuits have shown considerable promise; however, they require corresponding advancements in integrated

Primary Sound Standard Based On Dynamic Fabry Perot Interferometry

Author(s)
Akobuije Chijioke, Richard A. Allen, Steven E. Fick, Benjamin Reschovsky, Jared Strait, Randall P. Wagner
We describe an optical sound standard in which the sound pressure is measured by using a high-finesse optical cavity to observe the induced change in the

Optical-cavity-based primary sound standard

Author(s)
Akobuije Chijioke, Richard A. Allen, Steven E. Fick, David Long, Benjamin Reschovsky, Jared Strait, Randall P. Wagner
We propose an optical sound standard in which the sound pressure is directly measured by using an optical cavity to observe the induced change in the refractive

Serrodyne Frequency Shift Spectrometer and Serrodyne Frequency Shifting

NIST Inventors
Sean Bresler , John R. Lawall , Benjamin Reschovsky and David Long
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

Calibration Apparatus And Calibrating A Laser Doppler Vibrometer

NIST Inventors
Michael Gaitan , Benjamin Reschovsky and Akobuije Chijioke
A calibration apparatus for calibrating a laser Doppler vibrometer includes: a frequency shifter stage that: receives, from the laser Doppler vibrometer, primary laser light; produces frequency shifted light; communicates the frequency shifted light to a reflector; receives frequency shifted light

Sound Pressure Metrology Instrument And Determining Sound Pressure From Index Of Refraction

NIST Inventors
Richard A. Allen , Randall P Wagner , Benjamin Reschovsky and Akobuije Chijioke
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

Direct Digital Chirp Synthesizer And Generating A Chirped Optical Frequency Comb

NIST Inventors
David Long and Benjamin Reschovsky
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

Calibration Apparatus And Calibrating A Laser Doppler Vibrometer

NIST Inventors
Michael Gaitan , Benjamin Reschovsky and Akobuije Chijioke
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
