This is a laser ultrasonics experiment where the project aims are to measure many channels of GHz ultrasound to help to improve data acquisition rates and to allow a wider range of experiments to be performed. This involves research into both electronic and optical developments.
Thesis describes the combination of an optical system and artificial neural network to dramatically increase the measurement range of the optical system. Track width structures as small as 60nm were successfully measured with an optical system of 0.3 NA.
