Paper Abstract

We present an experimental set-up for the optical detection of condensed vapours or liquids and their refractive indices using photorefractive crystals (e. g. Barium-Calcium-Titanate or Barium-Titanate). Hereby we use a self-pumped phase conjugating mirror along with the effect of total reflection. The modulation of the signal beam in order to avoid background illumination is not necessary due to the phase-conjugated reflection. The detection of different condensed vapours or liquids and their refractive indices is possible by the variation of the input angle of the signal beam.
