Course review:
Wave optics phenomena used in optical measurement methods. Definition of basic terms of optical coherence, interference and diffraction in the near and far field. Elements of Fourier and Statistical Optics. Holography and related measurement methods. Holographic principle of recording and reconstruction of optical waves. Classification of holograms, their properties and methods of recording. Types of analogue recording materials and their properties. Problems of digital hologram recording and its reconstruction. Methods of holographic interferometry, its principles and utilization. Fresnel incoherent correlation holography (FINCH), its principle and use. Modern methods of holographic interferogram analysis. Application of holography in industry - measurement of deformations, vibrations, flow, holographic topography, non-destructive holographic defectoscopy. Other uses of holography - space filtration, holographic filters and memories, correlators, microscopy. Applications in biomechanics. Speckle and related measurement methods. Physical origin of phenomenon, terminology, statistical description in coherent and partially coherent light. Application potential of speckle in physics (optics, mechanics, astronomy), in medicine, biology or ecology. Punctual and areal measurement methods - Speckle correlation, Speckle photography, interferometric methods (ESPI, Shearography). Methods for detection of static and dynamic changes in surface conditions of objects (translation, rotation, deformation, speed, acceleration), defectoscopy. Principles and use of these methods. Correlation analysis of signals. Evaluation methods of correlograms, phase shift technique. Fluid and gas flow analysis, methods using Doppler effect (LDA) and induced fluorescence (LIF). White-light interferometry, white-light interferometry with spectral decomposition.
