  2. 1. Study of High Efficiency Phase-Only Diffractive Optical Elements

    Author : J. Michael Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; array illuminators; computer generated phase holograms; computer simulations; diffractive bifocal intraocular lenses; kinoforms; design; manufacture; diffractive optical elements; evaluation; simulation;

    Abstract : This work deals with the design, simulation, manufacture, and evaluation of diffractive optical elements. Particularly, kinoforms and diffractive bifocal intraocular lenses are studied. Evaluation of kinoforms, i.e. READ MORE

  4. 2. Diffractive Optics Design

    Author : Jörgen Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer-generated waveguide hologram; diffractive optics; fan-out; millimeter wave radiation; proximity effect; optimal-rotation-angle method; kinoform; integrated optics; beam shaping; outcoupling grating; scalar optics;

    Abstract : Diffractive optical elements (kinoforms) change the way light propagates, and can perform very complex tasks. They can split an incident beam into any number of outgoing, and possibly focused, beams (fan-out). READ MORE

  5. 3. Diffractive Optical Elements: Fabrication, Replication, and Applications and Optical Properties of a Visual Field Test

    Author : Fredrik Nikolajeff; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perimetry; beam homogenizing; antireflection; high-pass spatial frequency target; proximity effect; electron beam lithography; replication; successive development; diffractive optical element; axicon;

    Abstract : This thesis mainly treats the fabrication, replication and applications of diffractive optical elements. A smaller part deals with optical properties of a visual field test. Diffractive optical elements are computer-generated micro-optic components that use diffraction to manipulate light. READ MORE

  6. 4. Dynamic and Static Diffractive Optics - some Examples

    Author : Björn Löfving; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subwavelength grating; spatial light modulator; phase retrieval; diffractive optics; ferroelectric liquid crystal; analog-to-digital conversion; optical switch; feedback generated hologram;

    Abstract : Diffractive optics is a modern branch of optics, that exploits microstructures to manipulate the propagation of light. Fast computers and the progress in manufacturing technique of microelectronics have made possible a rapid development of diffractive optics during the past 10 years. READ MORE

  7. 5. Statistical optics and optical elements for microtechnologies: Partial coherence, lithography and microlenses

    Author : Christer Rydberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse methods; microlenses; optical propagation; partial coherence; dynamic speckle; lithography;

    Abstract : The scientific problems treated in this thesis are expressed within the framework ofstatistical optics and are generated out of the optical lithography industry. Opticallithography uses partially coherent light, i.e. light with a random wavefront, toincrease the performance of the lithographic process. READ MORE
