Paper Abstract

The particular family of liquid crystalline filters is presented. Their basis application is multiresolution image analysis (wavelet transform). That filter creates polarized beam of light, which constitutes the Haar wavelet. Simulation of such a filter by means of 4 X 4 matrix is presented as well as experimental results. The picture of the filter in polarized light is shown below in Fig. 2. In cooperation with phase shifter the polarization of the light beam may be rotated in the filter to extract image's features.
