| Abstract: | A particle image velocimetry (PIV) measure system in fluid field is proposed,which is based on the PIV technology.The PIV measure system in fluid field is suitable for the high-speed,hermetical water tunnel experimentations.It is composed of light source subsystem,imaging subsystem,image processing and analyzing subsystem,control subsystem and particles sending subsystem etc.,and it has high measure precision and high display capability in the entirely complex flow field without touching and disturbing.The measure error is less than 2%. |

| Keywords: | Particle image velocimetry(PIV) Flow field Water tunnel Automatic underwater vehicle |
