IPC: G01R29/12
Filed: 1987-12-15
Abstract: A voltage sensing device comprising a liquid crystal cell (10) electrically connected to a charged surface and having a light transmissivity varying with applied voltage. A light source (30) is directed through the liquid crystal cell, and a light detector (32) detects changes in the intensity of light directed through the cell and providing an output indicative of variations in voltage on the charged surface. Polarizers (24, 26), which polarize light from the light source directed through the liquid crystal cell, and analyze light exiting the cell, convert electro-optically induced phase changes into intensity changes. A saturation level biasing voltage is periodically applied to the liquid crystal cell to set the cell to a reference level, clearing the cell of transient polarization effects. A second reference liquid crystal cell may be provided, electrically coupled to a reference voltage. Signals from the charged surface derived by the liquid crystal cell connected to the surface are compared with reference signals derived by the reference cell prior to output of the signal to eliminate a time-based drift component from the output.

Abstract: Phase-change type, reversible optical infor­mation recording medium, being possible for recording, reproducing, erasing, and rewriting of information, by use of a laser beam. This invention consists of recording thin film of ternary compositions, for example, containing Ge, Te, Bi or quaternary compositions containing the fourth element of Se with which a part of Te is replaced, which is established on such surface - flat substrates as glass or plastics. In this case, the component ratio of Te and Se is selected not to be excess for other elements, such as Ge, Bi so as to be fixed as stable compounds of stoichiometric composi­tions of GeTe, Bi₂Te₃, or GeSe, Bi₂Se₃ when crystallized. Strictly speaking, a concentra­tion of each component is selected to have proper ratio of the number of atoms relative to each other so as to represent whole composition as the sum of each component. By this treatment, it is possible to have high crystallization speed and long cyclability of recording/erasing. The effect of Se is to increase the viscosity of the system and to make easily to obtain amorphous state; and moreover, by selecting of proper amount replaced with Te, it is possible to obtain the composition of recording film superior in both characteristics of recording (amorphiza­tion) and erasing (crystallization).
