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

Calibration Apparatus And Calibrating A Laser Doppler Vibrometer

NIST Inventors
Michael Gaitan , Benjamin Reschovsky and Akobuije Chijioke
A new approach to characterize the performance of a laser Doppler vibrometer (LDV). The method uses two acousto-optic modulators to frequency shift the light from an LDV by a known quantity to create a synthetic velocity shift that is traceable to a frequency reference. Results are presented for
