Abstract

Ultrasonic in-plane motion of a surface illuminated by laser light can be measured by monitoring the resulting dynamic speckle pattern with silicon-on-insulator photoconducting mesas without a reference beam. The statistical properties of the speckle pattern are exploited to calibrate the amplitude of velocity and displacement measurements.
