Title: Vortices in coherent and partially coherent optical beams
Author: Stahl, Charlotte
Date Created: 2018
Subjects--Topical: Optics
Description: Vortices in optical beams have been the subject of extensive study since their status as a generic feature of light was established. They have found extensive use in optical trapping systems, astronomy, microscopy and are being investigated for fr...

Title: OPTICAL PERFORMANCE OF RANDOM ANTIREFLECTION STRUCTURED SURFACES ON OPTICAL FLATS AND DIFFRACTIVE COMPONENTS
Author: KUNALA, KARTEEK
Date Created: 2018
Subjects--Topical: Optics
Description: Random anti-reflection surface structures (rARSS) are non-periodic, densely packed, sub-wavelength structures, fabricated on an optical surface. Light incident to such a boundary propagates from superstrate to substrate through a gradient effectiv...

Title: OPTICAL PERFORMANCE OF RANDOM ANTIREFLECTION STRUCTURED SURFACES ON NON-VITREOUS SUBSTRATES AND FUSED SILICA MICROLENS ARRAYS
Author: Eckart, Abigail
Date Created: 2018
Subjects--Topical: Optics
Description: Random anti-reflection surface structures (rARSS) are randomly spaced, densely packed, sub-wavelength cylindrical or conical features that are fabricated on the surface of optical substrates. As light passes from the superstrate to the substrate m...

Title: Minimizing Task-Specific Uncertainty in CMM-Based Freeform Optics Metrology
Author: Uwakwe, Michael
Date Created: 2018
Subjects--Topical: Mechanical engineering, Optics, Metrology
Description: Measurements of surface form involve a comparison between the form of the test surface and a reference. In coordinate measuring machine (CMM) measurements, this reference is the machine geometry. The measurement results typically show a height map...

Title: Microspherical Photonics for Enhancing Resolution of Optical Microscopy and Sensitivity of Focal Plane Arrays
Author: Brettin, Aaron
Date Created: 2018
Subjects--Topical: Optics
Description: It is shown that the resolution of virtual images of dye-doped dielectric nanospheres obtained through dielectric microspheres can be increased beyond the classical diffraction limit by decreasing the period of nanoplasmonic array used for localiz...

Title: Metasurfaces for Field Control and Detection
Author: Rosenbury, Christopher
Date Created: 2018
Subjects--Topical: Optics, Nanoscience, Physics
Description: Metasurfaces have been of increasing interest in the scientific community due to their consistent ability to efficiently reproduce traditional optical elements via quasi-monolithic patterning. In this dissertation I will examine various metasurfac...

Title: LOW UNCERTAINTY SURFACE AREA MEASUREMENT USING DEFLECTOMETRY
Author: Pouya Fard, Ali

Subjects--Topical: Optics, Engineering, Metaphysics
Description: Deflectometry has been introduced as a viable alternative to interferometric measurement of specular freeform optical surfaces. Deflectometry measurements show high repeatability; however, due to the errors remaining after the calibration and data...

Title: LIGHT-ASSISTED DRYING (LAD) FOR THE STABILIZATION OF PROTEINS IN AMORPHOUS TREHALOSE
Author: Young, Madison
Date Created: 2018
Subjects--Topical: Optics
Description: We have developed a new processing method, light-assisted drying (LAD), to create an amorphous trehalose matrix for the stabilization and storage of proteins. A challenge in the development of protein-based assays and therapeutics is preserving th...

Title: Improving Thulium Fiber Laser Lithotripsy Efficiency
Author: Hardy, Luke
Date Created: 2018
Subjects--Topical: Optics
Description: Kidney stone disease affects approximately 10% of the U.S. population. Conventional Holmium:YAG infrared laser lithotripsy is a standard minimally invasive treatment that operates based on a photothermal interaction with the main chromophore in ti...

Title: IN-SITU MEASUREMENT OF DIMENSIONS AND SURFACE PROFILE OF AXISYMMETRIC OBJECTS USING FRINGE PROJECTION TECHNIQUE
