Recent research by Joseph Vignola at the Catholic University of America is revolutionizing fresco assessment. Vignola and his team have applied laser Doppler vibrometry to locate delamination in ...

The frequencies of the two laser beams are Doppler shifted for point P, which moves at velocity v through the intersection point of the two laser beams. The downstream beam is frequency shifted up and ...

Laser vibrometry or more specific laser Doppler vibrometry is a precision optical measurement technology used for determining vibrational velocity and displacement at a fixed point. The laser Doppler ...

Laser-doppler vibrometers can be used to get a better understanding of inner ear biomechanics, as these instruments are high sensitive sensors and do not affect the specimen in any way.

A project at NIST has now demonstrated an alternative laser-based technique, and reported the results in acoustics journal JASA Express Letters. The new method involves scanning laser Doppler ...
