  • Polarization Lecture Outline
    1/31/20 Polarization Lecture outline • Why is polarization important? • Classification of polarization • Four ways to polarize EM waves • Polarization in active remote sensing systems 1 1/31/20 Definitions • Polarization is the phenomenon in which waves of light or other radiation are restricted in direction of vibration • Polarization is a property of waves that describes the orientation of their oscillations Coherence and incoherence • Coherent radiation originates from a single oscillator, or a group of oscillators in perfect synchronization (phase- locked, or with a constant phase offset) • e.g., microwave ovens, radars, lasers, radio towers (i.e., artificial sources) • Incoherent radiation originates from independent oscillators that are not phase-locked. Natural radiation is incoherent. 2 1/31/20 Why is polarization important? • Bohren (2006): ‘the only reason the polarization state of light is worth contemplating is that two beams, otherwise identical, may interact differently with matter if their polarization states are different.’ • Interference only occurs when EM waves have a similar frequency, constant phase offset and the same polarization (i.e., they are coherent) • Used by active remote sensing systems (radar, lidar) Classification of polarization • Linear • Circular • Elliptical • ‘Random’ or unpolarized 3 1/31/20 Linear polarization • Plane EM wave – linearly polarized • Trace of electric field vector is linear • Also called plane-polarized light • Convention is to refer to the electric field vector • Weather radars usually

  • Boundary Extraction and Polarimetry in Translucent Specimens for Photoelastic Stress Analysis
    Boundary Extraction and Polarimetry in Translucent Specimens for Photoelastic Stress Analysis Ahmed Ghali1, Tony P. Pridmore1, I. Arthur Jones2, Peiji Wang2 and Adib A. Becker2 1School of Computer Science and IT, University of Nottingham, Nottingham, NG1 8BB, UK 2School of Mechanical, Materials, Manufacturing Engineering and Management, University of Nottingham, Nottingham, NG1 8BB, UK ABSTRACT We address the problem of providing input to a novel method of interpreting photoelastic data for performing experimental stress analysis of models of engineering components. This method employs conventional photoelastic data relating to the directions of the principal stresses in the specimen (isoclinic data), along with the difference in principal stresses (isochromatic data). Both are used within an inverse boundary element model to reconstruct the load conditions at the model boundary and hence to recover the principal stresses in the specimen without recourse to numerical integration of shear stress gradient. We describe methods of obtaining unwrapped isoclinic and isochromatic phase maps from sequences of images captured within a computer-controlled polariscope. A boundary element model of the specimen, congruent with the isoclinic and isochromatic phase maps, is obtained from an image captured within the polariscope under either traditional lighting conditions or by configuring the polariscope to provide a light field background. Image segmentation reveals the boundary of the specimen, which is then described in terms of simple geometric primitives. Boundary points and geometric descriptions are both used to produce the final boundary element model. The techniques described have been applied to a number of contact specimens; results are presented and discussed. Keywords: stress analysis, photoelasticity, image segmentation, boundary representations 1.
