Characterization of Wideband All-Fiber Waveplates
Many commercial and laboratory applications of fiber optics require an ability to manipulate, change and control the state of polarization of light. This is usually accomplished with bulk-optic wave plates which are inherently narrowband, bulky, and often require careful manual tuning and …

A Prototype Polarimetric Camera for Unmanned Ground Vehicles
… are increasingly employing a combination of active sensors such as LIDAR with passive sensors like cameras to perform at all levels of perception, which includes detection, recognition and classification. Typical cameras measure the intensity of light at a variety of different wavelengths …

Polarimetric Characterization Of Random Electromagnetic Beams And Applications
Polarimetry is one of the principal means of investigating the interaction of light with matter. Theoretical models and experimental techniques are presented in this dissertation for polarimetric characterization of random electromagnetic beams and of signatures of random media in different …

Polarization control and measurement with meta-optics
Metasurfaces are artificially engineered arrays of subwavelength phase-shifting elements which, if designed with explicit polarization dependence, provide a fascinating platform for new polarization optics. In this thesis, we present metasurface diffraction gratings designed to produce arbitrarily …

Polarization of D(d,n)He³ reaction neutrons
The state of polarization of neutrons emitted at an angle of 45° (Lab) from the D(d,n)He³ reaction has been determined by observing the asymmetry in scattering from carbon. Neutrons scattered at equal angles to the right and left were detected simultaneously by two cylindrical stilbene crystals, …

Wide Viewing Angle Liquid Crystal Displays
… technologies are applied to the designs of wide viewing angle and high transmittance liquid crystal displays. First, a design of wide viewing angle liquid crystal displays utilizing crossed linear polarizers is proposed. The designed multi-domain vertical-alignment liquid crystal display …

Polarimetry Of Random Fields
… average quantities are accessible. The study of polarimetry is concerned with both the description of electromagnetic fields and the characterization of media a field has interacted with. The polarimetric information is conventionally presented in terms of second order field correlations which …
