New Techniques In Digital Holography

This book proposal for the “instrumentation & measurement” collection of ISTE-Wiley is devoted to special techniques in digital holography. The co-authors aim at establishing a synthetic stat-of-the-art of important advances in the field of digital holography. We are interested in detailing advances related to fundamentals of digital holography, in-line holography applied to fluid mechanics, digital color holography, digital holographic microscopy, infrared holography, special techniques in full field vibrometry and inverse problems in digital holography.

This book presents advanced techniques in the field of digital holography. The book is organized in 8 chapters. The fist chapter introduces the basic fundamentals of digital holography. Chapter 2 discusses about the use of in-line holography to the study of seeded flows; the recent developments permit to apply this technique in many industrial or laboratory situations for velocimetry, particle size measurement or trajectography. Chapter 3 presents the new perspectives in 3-color holography applied to solid mechanics and fluid mechanics. Especially, a comparison between Michelson interferometer and interferometer using Wollaston prisms will be discussed. Chapter 4 is devoted to special techniques in holographic microscopy, with use of partial spatially coherent light sources; the use of a reduced coherence source is of interest for reducing the measurement noise; typical applications are detailed. Chapter 5 is devoted to applications of holographic microscopy in neurosciences. Chapter 6 presents digital holography in the infrared domain. Technology related to sensors and light sources are presented and digital holographic infrared interferometry is detailed and applied to high amplitude displacements of industrial aeronautic structures. Examples in NDT (non destructive testing) are also provided. Chapter 7 of the book, aims at presenting new techniques in the field of vibration measurement; especially, techniques based on high speed and ultimate sensitivity are described. Examples related to life sciences are discussed. Chapter 8 discusses about inverse problems in digital holography and demonstrates how a priori knowledge can be used to recover full information of the object scene even when recording is sparse.
