FIELD: measurement technology. ^ SUBSTANCE: method is based upon orientation of liquid crystals disposed between two substrates. Diffraction gratings with line frequency higher than 500 lines/mm and height of micro-relief of 0,1-04, mc are formed onto the surfaces of substrates. Gratings are disposed to have gap of 10-50 mc and at random angle. Liquid crystals are oriented along lines of gratings. ^ EFFECT: improved reproducibility of cell. |
