Research output: Contribution to conferenceSpeech


This paper will examine the principles and prospects for optically generated and detected ultrasound
in the context of the characterisation of microscale structures. The objective of the work
reported here has been to assess the applicability of this technique to implement non-contact
measurements of multiple mechanical parameters, particularly in plate-like samples. Parameters
of interest may include: layer thickness; layer modulus, Poisson ratio and density.
