Introduction,in this book were developed decades ago, their application to the analysis of phenomena in heat- and mass-transfer becomes more and more common. This originates from several reasons. The most important one - common to all optical techniques — is that they work non-intrusively and therefore do not in

Fundamentals of Holography and Interferometry,optical arrangements for such experiments are shown. The techniques of data acquisition and evaluation are discussed. Examples demonstrate the advantages of the techniques used. Holographic interferometry has displaced Mach-Zehnder interferometry completely due to its greater cost effectiveness, sim

Evaluation of holograms by digital image processing,alysis and image processing in many technological and scientific areas. (s. Table 6.1). Numerous problems of pattern recognition, data handling of digitized pictures and computer graphics, formerly reserved for computing centers, TV stations or military organizations, can now be solved on a personal

Light Scattering,cles-crystals, aerosols, molecules, atoms etc.-is partially “deflected” or absorbed. In addition to a change in direction a change in frequency is also possible depending on the scattering process. The evaluation of the scattered light with regard to its intensity, wavelength, and direction often yi

用肘

Phase Doppler Anemometry (PDA),d (PDDM) and Phase Doppler Interferometry (PDI), is a laser optical instrument for simultaneous measurement of the velocity and size of spherical particles. Additionally it can be used for concentration and mass flux measurements.

Dynamic Light Scattering,the sample to be determined. The theoretical foundations of this method were laid at the beginning of the century, but the high resolution required to detect and measure the small frequency shifts and narrow spectral linewidths of the scattered light imposed stringent demands on both the light sourc
