An analysis of the spectral-time characteristics of a Fabry–Perot interferometer (FPI) in pulsed illumination is given. Processes that occur in the transit of light pulses of different widths through a FPI are considered in detail. A relationship between the baseline of a FPI and the width of the incident light pulse is established. The time structure of a pulse that has traversed a FPI is analyzed. The theoretical difference in the transit of a light pulse through a FPI and of a regular sequence of synchronized laser pulses is found. The maximum time resolution of a FPI is determined. A model that describes the transit of a regular sequence of synchronized laser pulses through a FPI functioning in the mode of an optical filter is determined.
