1. 1. Laboratory starlight simulator for future space-based heterodyne interferometry

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :William Karlsson; [2023]
   Nyckelord :Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

   Sammanfattning : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. LÄS MER

3. 2. Thermomechanical Design and Analysis of the Lisa Phase Measurement System

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Pablo Martinez Cano; [2019]
   Nyckelord :LISA; PCB; temperature; passive; aluminum; aluminium;

   Sammanfattning : Gravitational Waves (GWs) are ripples in the curvature of spacetime that propagate as waves at the speed of light while travelling basically undisturbed from the moment of their creation by accelerated masses. GWs provide unique information about astrophysical sources, such as binary systems, allowing their exploration under a wide range of masses, mass ratios and physical states inaccessible otherwise and therefore opening a new window to observe the universe.
