摘要: Thermochromic liquid crystals (TLCs) can serve as a light valve when it is carefully controlled by temperature. With a photodiode used in light transmissive intensity electric output voltage extraction, there is a progressive increase in output voltage from 19.331 to 35.800 degrees C, and the resolution is 0.0001482 degrees C, which decreases progressively to 0.03086 degrees C. If we design a linear integrated circuit with many very small sections for converting nonlinear extraction voltage to its relative temperature automatically, this system can serve as a thermometer. The whole system can be made portable for radiation temperature measurement.
