Abstract

Recent progresses in using photo-electromotive-force (photo-EMF) sensors for a variety of laser metrological applications are discussed. We'll present an overview on the device physics for photo-EMF sensors and discuss recent experimental results on several fronts, including highly sensitive pulsed laser vibrometers for surface vibration monitoring and laser ultrasonic diagnostics, interferometer-less coherent optical distance range finder with sub-laser wavelength precision, as well as laser Doppler velocimetry studies on hard surfaces.
