Holographic Interferometry

Transparent in the visible range phase objects can be studied in the optical range using holographic interferometry. Typically the holograms are recorded on high-resolving-power holographic photo materials but a lower spatial resolution is sufficient for successful research in many scientific applications. Holographic Interferometry: A MachâZehnder Approach offers practical guidance to research scientists and engineers using MachâZehnder holographic interferometry methods to study phase objects in the laboratory. The MachâZehnder approach allows the use of standard photographic film and electronic CCD/CMOS sensors with low resolving power making it a simpler and more affordable option for testing many types of phase objects. This book demonstrates how to use standard photographic film for the optical recording and reconstruction of MachâZehnder holograms. It also illustrates techniques for using CCD/CMOS cameras to digitally record MachâZehnder holograms/interferograms of transparent objects. Bringing together original research and information scattered throughout existing literature this book focuses on the holographic reference beam and shearing interferometry methods. In particular it looks at how these methods and optical schemes can be directly applied to testing aerodynamic flows as well as to plasmas shocks and waves in noncoherent laserâmatter interactions. Numerous reconstructed and classic interferograms deflectograms and Schlierengrams illustrate the material helping readers develop and design their own optimal optical scheme and choose applicable details to apply the approach. Describing methods in a mathematically simple and accessible way this book is also suitable for graduate students in the fields of aerospace engineering and optics as well as those in laser thermal and plasma physics. .
