Three component flow mapping - Experiences in stereoscopic PIV and holographic velocimetry
Abstract
Two approaches to three-component velocity measurements are examined. One approach involves the application of stereogrammetry to particle image velocimetry (PIV). An alternative approach employs a stereo holography imaging system which allows the simultaneous recording of two holograms using in-line recording methods. It is shown that both methods are capable of providing three-dimensional information flow. Optical implementations of the methods and data processing are discussed.
