- •
A non-contacting all-optical method for acoustic monitoring of an apple is presented.
- •
Elastic wave velocities can be used to estimate an apple's elastic properties.
- •
Elastic wave attenuation and mode Q factor estimate an apple's anelastic properties.
- •
Apple ripeness decreases wave amplitude at a greater rate than wave velocity.
