Book Description
This manual describes the procedures and components necessary to produce a holographic interferogram of a flow field in the Sandia National Laboratories hypersonic wind tunnel. In contrast to classical interferometry, holographic interferometry records the amplitude and phase distribution of a lightwave passing through the flow field at some instant of time. This information can then be reconstructed outside the wind tunnel for visual analysis and digital processing, yielding precise characterizations of aerodynamic phenomena. The reconstruction and subsequent hologram image storage process is discussed, with particular attention paid to the digital image processor and the data reduction technique.

Book Description
Holographic interferometry was successfully applied to a large-scale wind tunel (40-cm x 40-cm test section) experiment on a three-dimensional flow field. The laser interferometer was set up in a schlieren bench with a pulsed-ruby laser as the light source. Both the object beam and the reference beam were collimated. The conventional double-exposure, off-axis operation was used to produce interferograms...
