The master level optics laboratory is a biannual, intensive laboratory course in the fields of geometrical, physical and modern optics. This course is intended for the master level student though Ph.D. advisors which often recommend it to their advisees. The students are required to complete five standard laboratory experiments and an independent project during a semester. The goals of the laboratory experiments are for the students to get hands-on experience setting up optical laboratory equipment, collecting and analyzing data, as well as to communicate key results. The experimental methods, analysis, and results of the standard experiments are submitted in a journal style report, while an oral presentation is given for the independent project.
We explore how a class of unconventionally polarized beams can be applied to such problems as aerosol polarimetry. One such beam can be formed by the superposition of right and left circular-polarized beams combined in a Twyman-Green Interferometer, and adjusted with linear tilt. Such superposition results in a beam that repeatedly traverses the equator of the Poincaré sphere in one of the beams spatial dimensions, such that an image of light scattered from the beam can yield the phase function of the scatterers without temporal modulation of the input polarization. An equivalent, but more robust method, uses a specially designed Nomarski prism arrangement to introduce a known angular shear between right and left circularly polarized fields.
