FUNDAMENTALS OF INTERFEROMETRY AND HOLOGRAPHY FOR CIVIL AND STRUCTURAL-ENGINEERING MEASUREMENTS

A basic foundation for holography, interferometry and speckle measurem ent is provided to assist those readers who do not have an optics back ground. The inclusion of this introductory material is also intended t o reduce the amount of repetitive material that would have been requir ed by the subsequent authors. The principles of many optical diagnosti cs measurements can be understood simply and with very little mathemat ics, by using graphics and moire analogies-these are used extensively here. The physical and mathematical analogy between interferometry and moire is exploited to provide a simple, easily demonstrable explanati on of virtually all of the phenomena in interferometry and holography.
