Students of the PAL lab have become the first apple seismologists after publishing our paper on acoustic monitoring of apples using laser ultrasound in Postharvest Biology and Technology. This paper shows how to infer an apples firmness using elastic wave propagation, a technique developed by seismologists to interrogate the earth using earthquakes. In this case we generate and detect ‘applequakes‘¬†using high energy lasers and sensitive detectors. Congratulations to Sam and Zoe for completing such an interdisciplinary project.
