Detection of ultrasonic motion of a scattering surface using two-wave mixing in semiconductor photorefractive material under an applied field

Not Accessible

Your library or personal account may give you access

Abstract

The generation and the detection of ultrasound at distance by lasers present many advantages over conventional piezo electric based methods. In particular, this technique can be used on surfaces of complex geometry and on products at elevated temperature on a production line.1
