Resumen:

In this work we propose the use of a photoacoustic implementation to rapidly estimate, without contact, mechanical properties of plant leaves. We implemented a laser-based ultrasound setup, operating in thermoelastic regime, to remotely generate and detect plate waves. For both, the midrib and lamina of arabica coffee leaves samples, we performed linear and circular scans in order to obtain the characteristic diagrams in time and frequency domains, the propagating patterns, and the effective elastic constants of the tissues under study.
