Abstract. An analysis is made of the method for obtaining the dependence of the intensity on the time of the pulses acting on the system from the response of the system. The shape, frequency and intensity of the pulses vary in an arbitrary way. The pulse duration is shorter than the relaxation time of the system to a steady state. The optical impulses are reconstructed from the time dependence of the conductivity of the photoresistor. The photoconductivity kinetics in this case is determined by the dependence of the rate of generation on time and depends to a small extent on the rate of recombination of electrons and holes. Analysis of the emission of a luminescent source makes it possible to obtain a time dependence of the intensity of ultraviolet radiation causing luminescence.

Keywords: impulse excitation, recombination mechanisms, kinetics of photoconductivity, distortions, recovery of impulse.
