Aim: Introduce the participants to modern physical optics, i.e. theory of diffraction, coherence, Fourier optics, optical information processing and -storage. The principles are demonstrated by use of coherent light sources (lasers) in experimets for optical processing, measurements and holographic data storage.
Based on the physical optics we describe a number of optical measurement methods. We explain the differences using incoherent and coherent light and present some practical applications. The course is directed both towards the future project manager working with development projects and the user of advanced optical equipment. The main goal is the understanding of the physical background and limitations of the measurement methods. In addition, the course stresses knowledge of practical applications and planning and execution of advanced measurements. |
Contents: Coherence theory, scalar diffraction theory, Fourier transform by a lens, optical processing of two-dimensional information fields, spatial spectral analysis and filtering, application for image restoration and pattern recognition, holographic data storage with applications for recording of 3-D images, holographic optical elements (DOE).
Overview over optical measurements of mechanical, thermal and other quantities. Physical background including light sources, detection of light, analysis of noise and fluctuations in detector signals. Principles including measurements of distance, velocity, vibration. Methods using white light, interferometric methods, holographic methods and speckle interferometry. Fibre optics and fibre optical sensors. Doppler velocimetry and particle image velocimetry and methods using molecular scattering phenomena. Finally, processing and presentation of data and estimation of uncertainties in optical measurements. |
