This lesson covers the fundamental principles of Particle Image Velocimetry (PIV), a technique used to measure velocities in fluid flows. The lesson delves into the process of image capturing, processing, and the concept of interrogation windows. It further explains how captured images are divided into rectangular windows and correlated to form average displacement vectors. The lesson also discusses the importance of Fast Fourier Transform (FFT) processing in speeding up the correlation process. It highlights the differences between FFT processing in PIV and Laser Doppler Anemometry (LDA). The lesson concludes with an introduction to the cross-correlation algorithm, which is commonly used in PIV analysis.
