The document discusses particle image velocimetry (PIV), which is a non-intrusive method for measuring fluid flow velocities. PIV works by seeding the fluid with particles and using a laser sheet and camera to capture particle images. Software then tracks the particle movements between images to calculate velocity vectors across the flow field. PIV has applications in analyzing flows around objects like fish, helicopters, and prosthetic heart valves. Advanced PIV systems are being developed that can perform 3D motion tracking.

BACKUP2-Charged Coupled devices Charge coupled devices or CCD’s are arrays of semiconductor gates formed on a substrate of an integrated circuit or chip The charge collected and stored in each gate of the array represents a picture element or pixel of an image. IC (integrated circuit) and control circuits typically mounted on a printed wiring assembly for camera control. Add Your Title
