1. 1. Diffractive Optics Design

   Författare :Jörgen Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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). LÄS MER

5. 4. Optics Corrections and Stabilization Methods for Particle Accelerators

   Författare :Tobias Persson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; accelerators; beam optics; ; feedback; CTF3; optics correction; CLIC;

   Sammanfattning : The discovery of a Higgs-like particle is the result of excellent performance ofboth the LHC (Large Hadron Collider) and its detectors. A significant partof the success can be attributed to the excellent control of the optics in theaccelerator. In this thesis the methods used to correct the optics functions arepresented. LÄS MER

7. 5. Optics for Earth Observation Instruments

   Författare :Arvid Hammar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis; free-form mirrors; measurements; stray light; spline horns; THz; reflector optics; satellites; scientific instruments; diamond turning; tolerancing; telescopes;

   Sammanfattning : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. LÄS MER
