✦ Synopsis


Electrooptical Eehaviour of Aerosil i n a Two-frequency Addressing Mixture

The electrooptical behaviour of an aerosiljliqoid crystal mixture with low cross over frequency f is compared with that of a mixture with a high relaxation frequency. Thereby two parts of the transparency, the constant Tcon and the modulated Tch o n e , were measured. In both mixtures Tch decreases with increasing frequency, whereas only Tcon decreases in the frequency range around fo. The switching times for the two-frequency--switching are in the order of magnitude of few milliseconds (contrast 1: 10).
