3. 2. Laboratory starlight simulator for future space-based heterodyne interferometry

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : William Karlsson; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE
