Abstract
We evaluate a laser-generated ultrasound method for non-destructive fruit assessment. Unlike prior full-contour studies, this paper provides a non-destructive method for determining phase velocity and attenuation over a short linear segment of the surface. Trials on kiwi, banana, and avocado revealed strong attenuation sensitivity to viscoelastic differences. In avocados, postharvest monitoring showed measurable attenuation drops with ripening, while phase velocity remained stable. The method detected structural changes before visible softening and may support early pest damage detection and automated quality grading.
