A laser beam incident on a homogeneousely aligned cell of antiferroelectric liquid crystals is deflected at field-induced ferro-antiferro-electric phase transitions. Any diffraction effect due to herical structures does not account for the experimental results. From the experimental results of incident angle dependence of the deflection angles, it was concluded that the phenomenon is due to refraction and reflection of light at the phase boundaries between ferro- and antiferro-electric phases.
