Spread Function of the Optical Time-Dispersion Analyzer of Spectra and its Computer Modeling

The idea of transferring the dispersion-time method of changing the spectra of radio pulses to the optical range is considered, where an optical fiber is used as a dispersing medium. A computer simulation of the spread function of such an instrument as the evolution of truncated monochromatic radiation during its propagation in an optical fiber is performed. The results of computer simulation allow us to estimate the degree of approximation of a real spread function to an ideal one based on mutually correlated criteria.
