   Sammanfattning : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. LÄS MER

3. 2. Experimental Adaptive Optics. A test facility for adaptive optics on a small telescope

   Författare :Per Knutsson; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; imaging through turbulent media; wavefront sensing; active or adaptive optics; aberration compensation; astronomical optics;

   Sammanfattning : This thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. LÄS MER
