About this document
Thermal Wave Diagnostics in Materials by Revito88 is a document available to read on EtoBox.
This document discusses the use of thermal wave diagnostics and photoacoustic effect to detect defects in solid objects and biological tissues in a non-destructive manner. Thermal wave diagnostics utilizes the photoacoustic effect where a sample is illuminated by amplitude-modulated light, causing periodic heating and thermal expansion which generates acoustic waves. The thermal diffusion length, which determines the depth of detection, depends on the modulation frequency - allowing visualization depth to b
