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

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
