Title: A COMPUTATIONAL SPECTRAL IMAGING TECHNIQUE AND ITS APPLICATION IN FORM METROLOGY
Author: Habibi, Nasim
Date Created: 2017
Subjects--Topical: Optics
Description: Many existing systems for three-dimensional (3D) shape measurement require mechanical moving parts that limit the measurement speed. A non-contact optical system that does not requires any moving parts can, in principle, increase the speed of meas...

Title: DESIGN, TOLERANCING, AND EXPERIMENTAL CHARACTERIZATION OF DYNAMIC FREEFORM OPTICAL SYSTEMS
Author: Shultz, Jason
Date Created: 2017
Subjects--Topical: Optics, Engineering, Physics
Description: Although freeform concepts have been considered for many decades, new fabrication capabilities have enabled new classes of optical components and sparked greatly increased interest in freeform optics. Generally defined as surfaces without rotation...

Title: Exploiting Metamaterials: Fundamentals and Applications
Author: Karami, Morteza
Date Created: 2017
Subjects--Topical: Optics, Physics, Electromagnetism
Description: Metamaterials are man-made structures developed to engineer electromagnetic waves, and they have been studied intensely in recent decades. Although there are still debates about the performance of these types of artificial materials, many practica...

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: In Situ Fringe Projection Profilometry for Laser Powder Bed Fusion Process
Author: Zhang, Bin
Date Created: 2017
Subjects--Topical: Mechanical engineering, Optics, Engineering
Description: Additive manufacturing (AM) offers an industrial solution to produce parts with complex geometries and internal structures that conventional manufacturing techniques cannot produce. However, current metal additive process, particularly the laser p...

Title: Index-antiguided planar waveguide lasers with large mode area
Author: Liu, Yuanye
Date Created: 2017
Subjects--Topical: Optics, Physics
Description: The on-going research and application interests with high power large-mode-area (LMA) waveguide lasers, especially in fiber geometry, at the beginning of this century drive the development of many novel waveguide designs. Index antiguiding, propos...

Title: Interaction of femtosecond laser beam with atmospheric low temperature plasmas and electric fields
Author: Davda, Kirtan
Date Created: 2017
Subjects--Topical: Optics, Physics, Power resources
Description: In this work, the influence of electric fields and atmospheric plasma on the behavior of an ultrafast femtosecond laser beam is being studied. A femtosecond laser pulse has an ability to self-focus in air and produce confined narrow channels of hi...

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: SUBSURFACE THERMAL COAGULATION OF TISSUES USING NEAR INFRARED LASERS
Author: Chang, Chun-Hung
Date Created: 2017
Subjects--Topical: Optics, Biophysics, Biomedical engineering
Description: Noninvasive laser therapy is currently limited primarily to cosmetic dermatological applications such as skin resurfacing, hair removal, tattoo removal and treatment of vascular birthmarks. In order to expand applications of noninvasive laser ther...

Title: Stratified Fiber-Resonator: Fabrication, Characterization and Potential Applications
Author: Naqvi, Zeba
Date Created: 2017
Subjects--Topical: Optics
Description: Whispering Gallery Mode Resonators (WGMR) are compact, monolithic resonators used for photonic applications. Controlling the properties of WGM while keeping the geometry simple is desired to improve their performance, especially for sensing and no...

Title: THEORY AND NUMERICAL ANALYSIS OF INDEX-ANTIGUIDED WAVEGUIDE LASERS
Author: Wang, Chaofan
Date Created: 2017
Subjects--Topical: Optics
Description: Index-antiguided (IAG) waveguide is promising for high-power application due to simple step-index structure and the property to introduce higher waveguide loss for higher-order-modes (HOMs). The loss ratio between fundamental mode (FM) and 1st HOM...
