Abstract:: Using a plastic bottle, we explore the capabilities of a reflective phase-only Spatial Light Modulator (SLM) in removing wavefront aberrations using a Zernike polynomial phase mask, with the modulators phase depth limited to 0.8π radians. Wavefront aberrations, which can be modeled with Zernike polynomials, distort image transmission through various optical...

Creator:: Tucker, Derek A.
Abstract:: The optical characterization of transparent conductive thin films is demonstrated. The basics of transparency and conductivity, as they relate to transparent conductor research, are explained. A functional model of the reflectance and transmittance of a sample film, including interference fringes, is derived from the Fresnel electric field amplitude coefficients. The...

Creator:: Dempsey, Zackery E.
Abstract:: In recent decades, the cell phone has provided a convenient form of long-distance communi-cation to the general public. Despite the technological improvements since, cell phones and their smartphone successors have suffered from a lack of clarity over a typical voice call, a result of their limited bandwidth. New phone services,...

Creator:: Wells, Blake
Abstract:: A method for determining bandgap energy using diffuse reflection is presented. The method uses bifurcated fiber optic cables to measure the diffuse reflection of diffusely reflective materials. The absorption spectrum is extrapolated from the diffuse reflection spectrum and used to determine the bandgap of powdered materials. The theory of nonspecular...

Creator:: Prudell, Kathleen
Abstract:: A method has been developed to measure the thickness of ZnS thin films on Si using optical interference. Thin film optical interference fringes are dependent upon the thickness of the film, and for this reason the thickness can be determined by measuring reflectance spectrum of a thin film. A grating...

Creator:: Gruss, Daniel
Abstract:: Optical tweezers are capable of trapping micron sized particles through the transfer of the momentum of light. These capabilities are expanded through the use of computer controlled holograms for beam shaping. This hologram creation is facilitated through the use of a spatial light modulator, which is a liquid crystal device...

Creator:: Fettig, Doug J.
Abstract:: The LIGO interferometers have reached their designed sensitivity level which is greater than any other interferometer ever built. At this point, it is important to have a proper understanding of small perturbations that might still exist (until now these issues did not come to the forefront because other more critical...
