PIV techniques have been developed for one and half decades. The techniques have been applied to many kinds of fluid phenomena as its potential increases. High potential hardware such as a YAG laser, High resolution
We have high power lasers for ideal illumination, which can be controlled to emit spatially and temporally defined light pulses, high power computers, various kinds of non-standard video cameras, and tracers. Measurement objects range from micro scale objects to actual airplanes. A velocity range expands from micron per seconds to beyond sonic velocity.
Accelerated improvements in performances of hardware have changed PIV techniques. Applications of PIV to micron scale flows and multi-phase flows are shown in the paper.
Some issues for further expansion of the applications are discussed in the end of the paper; Special remarks are made for the motion measurement moving objects of flexible structures.
