4. 2. Adaptive Optics in Integrated Modeling of Telescopes

   Author : Anita Enmark; Astronomi - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; extremely large telescope; adaptive optics; Integrated model;

   Abstract : This thesis present the implementation of a modular adaptive optics (AO) model, as part of an integrated model of extremely large telescopes (ELTs). The purpose of the project has been to establish knowledge within integrated modeling, with emphasis on adaptive optics. READ MORE

5. 3. Study of a Large Deformable Mirror Concept

   Author : Rikard Heimsten; Astronomi - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Large deformable mirror - Adaptive optics - Distributed Control - Local control: actuator family - Faceplate: vibration modes - Faceplate: Dimensionless modal analysis;

   Abstract : It is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. READ MORE
