Title: Cutting Mechanics and Manufacture of Optics for Imaging Applications
Author: Troutman, John
Date Created: 2016
Subjects--Topical: Mechanical engineering, Optics
Description: Ultraprecision diamond machining enables physical realization of freeform surfaces of nearly arbitrary complexity through turning and milling processes. Achievable form accuracies make diamond machining a viable alternative to conventional techniq...

Title: FREEFORM MEASUREMENT WITH STITCHING TALBOT INTERFEROMETER
Author: Furukawa, Yasunori
Date Created: 2018
Subjects--Topical: Optics
Description: Freeform optics are being used in many fields to realize the outstanding performance due to their high degree of freedom. To realize sufficiently high performance, it is necessary to manufacture the freeform surface with high accuracy, which requi...

Title: From Nonradiating Sources to Directionally Invisible Objects
Author: Hurwitz, Elisa
Date Created: 2017
Subjects--Topical: Optics, Physics
Description: The goal of this dissertation is to extend the understanding of invisible objects, in particular nonradiating sources and directional nonscattering scatterers. First, variations of null-field nonradiating sources are derived from Maxwell's equatio...

Title: MID-SPATIAL FREQUENCY CHARACTERIZATION AND SPECIFICATION FOR FREEFORM SURFACES USING ZERNIKE POLYNOMIALS
Author: Hosseinimakarem, Zahra
Date Created: 2017
Subjects--Topical: Optics, Engineering
Description: Mid-spatial frequency on freeform optical elements induces small-angle scatter and affects the optical performance. Fabrication techniques involved in making freeform surfaces leave tooling marks on the surface due to the sub-aperture nature of th...

Title: NONPROPAGATING EXCITATIONS IN 2-D
Author: Abney, Ray
Date Created: 2020
Subjects--Topical: Physics
Description: Nonpropagating excitations have been studied in 1-D and in 3-D, but not so much in 2-D. So, this thesis concerns 2-D nonpropagating excitations. In particular, we construct nonpropagating excitations confined to an annulus under a time-independent...

Title: Numerical and Optical Performance Characterization of Random Antireflective Surface Structures on Diffractive Optical Elements
Author: Gadamsetti, Praneeth
Date Created: 2023
Subjects--Topical: Optics
Description: Antireflective structured surfaces (ARSS) are periodic, or random, distributions of three-dimensional nano-features fabricated directly on optical quality substrates, for the suppression of surface reflectivity from the dielectric boundary. Within...

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...
