Abstract

One of the ever present problems in laser ultrasonic techniques is the relatively poor signal to noise ratio, which means that in many cases the data acquisition rates are unacceptably slow or the necessary laser power can damage the sample. Here we present our approach to parallelising the detection process which can greatly speed up measurement times. We describe results using both a commercial detector array and custom arrays designed in house. The approach we have taken is generally applicable for a range of pump probe experiments and we give examples where applicable
