| Abstract: | A litle system was developed to determine the relationships of liquid crystal properties between dielectric coefficient and temperature or resistivity and temperature and to measure the electrooptical effects of liquid crystal materials. It was equipped with a waveform generator of arbitrary function as the power source. In the data processing system, methods for Weak signal detection are adopted to improve the accuracy. Experiments have indicated that the system has due practical value to the property measurement of liquid crystalmaterials. |
