説明

Some choresteric liquid crystals can be used as a thermometer because of their color changes with varying temperatures. However, it is impossible to employ human color sensation for precise quantitative evaluation of temperature from their color. Therefore, a new method of liquid crystal thermometry is developed using narrow band optical filters and an image processor to exclude the employment of human color sensation. Relations between filter wavelength and temperature were determined by calibration tests. Two dimensional temperature distributions on a heated plate were successfully measured by the present method.
