PIV Particle Image Velocimetry Using Line Lasers/Structured Light

Laser Particle Image Velocimetry (PIV) is a transient, multi-point, non-contact fluid dynamics measurement technique that overcomes the limitations of traditional single-point measurements. It enables the simultaneous recording of velocity distribution across numerous spatial points in a single snapshot, providing detailed insights into the complex spatial structure and dynamic characteristics of the flow field. PIV is widely applicable in fields such as wind tunnel flow measurements, turbulent flow analysis, granular flow studies, environmental research, and biomedical applications.
