SLONs
SLONs, or Synthetic-aperture Light-field Observational Nulling Systems, are an advanced astronomical instrumentation technique designed to enhance the detection and characterization of exoplanets. They combine the principles of synthetic aperture interferometry with the capabilities of light-field cameras. Synthetic aperture techniques effectively simulate a much larger telescope by combining data from multiple smaller, spaced-apart telescopes, significantly improving resolution. Light-field cameras, on the other hand, capture not only the intensity of light but also its direction, allowing for a more comprehensive reconstruction of the observed scene.
The "observational nulling" aspect of SLONs refers to a method used to suppress the overwhelming light from
