= Photoacoustic Doppler effect
{wiki=Photoacoustic_Doppler_effect}
The photoacoustic Doppler effect is a phenomenon that combines principles of photoacoustic imaging and the Doppler effect to provide information about the movement of scattering particles, such as blood cells, in a medium. It exploits the interaction between light and sound waves to measure dynamics at a microscopic level. \#\#\# Key Concepts: 1. **Photoacoustic Effect**: This is the generation of acoustic waves (sound) following the absorption of light (usually from a laser).
