Holographic Particle Image Velocimetry (HPIV) is potentially the best technique to
obtain instantaneous, three-dimensional, flow field information. Several researchers have
presented their experimental results to demonstrate the power of HPIV technique.
However, the challenge to find an economical and automatic means to extract and process
the immense amount of data from the holograms still remains. This thesis reports on the
development of complex amplitude correlation as a means of data extraction. At the same
time, three-dimensional quantitative measurements for a micro scale flow is of increasing
importance in the design of microfluidic devices. This thesis also reports the investigation
of HPIV in micro-scale fluid flow.
The author has re-examined complex amplitude correlation using a formulation of scalar
diffraction in three-dimensional vector space. [Continues.]
