Temperature Measurement and Accuracy with Thermo Sensitive Liquid Crystal

Recently, an electronic device is miniaturizing. simultaneously the object of temperature measurement became smaller, and more complex. The measurement of a minute area is difficult of the conventional temperature measuring method. It is already known that the temperature measuring method by thermo sensitive liquid crystal is effective in measurement of a thermal field. But a small field can not measure by conventional method. In this study the temperature measurement is enable by taking a picture of a smaller area by thermo sensitive liquid crystal. The object is temperature distribution of the natural convection. The temperature measurement is enable in a small area.
