Efficiency Research of Sun Protection Window Films for Speech Information Protection from LEAKAGE by Optoelectronic Channel

The paper deals with the issues of speech information protection from the leakage by optoelectronic channel. This channel is made by irradiating laser beam of the reflective surfaces inside the premises. A new method for protection of speech information against leakage through laser channel was proposed. This method made use of sun protection window films. The results of experimental research on sun protection window films for speech information protection from the leakage by optoelectronic (laser) channel are given.
