Course: Advanced topics in classical optics 1

Department/Abbreviation: SLO/PPO1X

Year: 2021

Guarantee: 'prof. RNDr. Miroslav Hrabovský, DrSc.'

Annotation: The aim is to give students information about selected basic optical measuring methods, their principles and utilization. Students recall basic optical phenomena (coherence, interference, diffraction). The course focuses on interferometric and holographic methods, methods based on speckle, etc. and their utilization in measurements of selected physical quantities (components of deformation tensor and quantities derived from them, etc.).

Evaluation of holographic interferograms. Holography of time-variable processes. Application of holography - verification of the shape, strain tensor (displacement, rotation, deformation), phase phenomena, application in thermomechanics, in measurements of vibrations and beats, etc. Incoherent correlation holography, computer (digital) holography and their usage.) SPECKLE (Speckle phenomenon - origin, historical view, basic terms and definitions. Subjective and objective speckle. Shift and decorrelation of speckle field. Statistical properties of speckle - first-order statistic and second-order statistics, theoretical model.
