Setup for measuring fruit firmness through the velocity of propagation of Rayleigh waves

Caption

A pulsed laser is focused by a lens onto a point close to the surface of the fruit. The laser-induced plasma creates a shockwave that excites Rayleigh waves on the surface of the mango, which are then measured using laser Doppler vibrometers.
