  • The 21st century is said to be a photon-century. People meet contemporary optics (holography, as well) applications everywhere. It would be appropriate to increase the common education level in this field for people to be able to understand new surrounding technologies, entering our everyday lives. Optics serves as an important part of many scientific experimental methods. This way, such information could be useful also for researchers without a professional optical education.

  • Holography has recently become a field of much interest because of the many new applications implemented by various holographic techniques. This book is a collection of 22 excellent chapters written by various experts, and it covers various aspects of holography. The chapters of the book are organized in six sections, starting with theory, continuing with materials, techniques, applications as well as digital algorithms, and finally ending with non-optical holograms.

  • This edition of Optical Metrology contains a new chapter about computerized optical processes, including digital holography and digital speckle photography. Chapter 2, on Gaussian optics, and Chapter 5, on light sources and detectors, are greatly expanded to include descriptions of standard imaging systems, light-emitting diodes and solid-state detectors. Separate new sections on optical coherence tomography, speckle correlation, the Fast Fourier Transform, temporal phase unwrapping and fibre Bragg sensors are included. Finally, a new appendix about Fourier series is given.

  • Holography Holography is the synthesis of interference and diffraction. In recording a hologram, two waves interfere to form an interference pattern on the recording medium. When reconstructing the hologram, the reconstructing wave is diffracted by the hologram. When looking at the reconstruction of a 3-D object, it is like looking at the real object. It is therefore said that: ‘A photograph tells more than a thousand words and a hologram tells more than a thousand photographs’.

  • 13 Brake Vibration Formal studies of brake vibration appear to have been first reported in 1935 by Lamarque and Williams, who were concerned with brake squeak [1]. Subsequent theoretical studies provided a mathematical formulation of the problem and further experimental data.

  • Speckle Methods When looking at the laser light scattered from a rough surface, one sees a granular pattern as in Figure 8.2. This so-called speckle pattern can be regarded as a multiple wave interference pattern with random individual phases. In the years following the advent of the laser, this pattern was considered a mere nuisance, especially in holography (and it still is!). But from the beginning of 1970 there were several reports from experiments in which speckle was exploited as a measuring tool.

  • Photoelasticity and Polarized Light Up to now we have treated the light field as a scalar quantity. The electromagnetic field, however, is a vector quantity which is perpendicular to the direction of propagation and with a defined orientation in space. This property is known as the polarization of light. In our treatments of interferometry and holography it is silently understood that the interfering waves have the same polarization. In practice, however, this condition is fulfilled to a greater or lesser degree....

  • Computerized Optical Processes For almost 30 years, the silver halide emulsion has been first choice as the recording medium for holography, speckle interferometry, speckle photography, moir´ and optical e filtering. Materials such as photoresist, photopolymers and thermoplastic film have also been in use. There are two main reasons for this success. In processes where diffraction is involved (as in holographic reconstruction), a transparency is needed. The other advantage of film is its superior resolution.
