Abstract
A system includes a detector and a computing device communicatively coupled to the detector. The detector detects spatial or temporal spectral features of a light beam after transmission of the light beam through a turbulent or aberrated medium and generate a measurement signal indicative of the spectral feature. The computing device receives the measurement signal and a comparative signal indicative of a spectral feature of the light beam prior to or after transmission of the light beam through the medium. The computing device compares the measurement signal and the comparative signal and determines, based on the comparison of the measurement signal and the comparative signal, one or more values related to variations in refractive indices of the medium.
