Title: Speckle Photo-electromotive-force For Large Transverse Vibration Amplitude Measurement
Author: Mosquera L.
Frejlich J.
Abstract: We report the use of photo-electromotive-force effect in a speckled pattern of light onto a photorefractive Bi 12TiO 20 crystal to measure the amplitude of transverse vibrations. Our theoretical model shows that, for vibrations much faster than the photorefractive response time, the photo-emf signal exhibits a maximum at a characteristic vibration amplitude value that may be used to calibrate the photo-emf sensor.
