Abstract:BackgroundIt is challenging to visually identify tiny and concealed foreign objects within the body due to their small size and subcutaneous location while they can cause infections.MethodsA non‐contact photoacoustic system based on Rosencwaig‐Gersho photoacoustic theory and dual modulator method is developed for detecting foreign objects in meat.ResultThe experiments conducted validate the successful development of this measurement technique with 10 μm spatial resolution and its corresponding mathematical mod… Show more
