We consider the applicability of laser transillumination method for the investigation of the screech-tones generation by the supersonic jet. Results of the experiments on parallel registration of the acoustic noise and laser radiation passed through the jet are discussed. The presence of responses at screech frequencies are found in the radiation spectra. Strong dependence of spectral amplitudes at screech frequencies from the sensing path shows high sensibility of laser sensing method for the selection of jet areas producing screech.
