SOFIA (Scanning Optical Frequency Interferometry Analyzer)

SOFIA (Scanning Optical Frequency Interferometry Analyzer) is a precise instrument that measures the frequencies of light sources with high accuracy. It works by splitting a light beam into two paths, then recombining them to create an interference pattern that reveals how the light's frequency changes over time or distance. By scanning different frequencies systematically, SOFIA can analyze the spectral properties of various light sources, helping scientists study phenomena like stellar atmospheres, molecular signatures, and fundamental physical processes with remarkable precision.
