Abstract

The liquid crystal thermography is a high-resolution and non-intrusive optical technique for full-field temperature measurement. We present detailed calibration data for a wide-bandwidth thermochromic liquid crystal (TLC) to investigate the effect of the coating thickness on the hue-temperature characteristics and the measurement uncertainty of the TLC. It is found that the coating thickness has appreciable effect on the TLC hue-temperature curve. For TLC coatings with the thickness over 20 ?m, a thicker TLC coating shows a relatively smaller measurement uncertainty, but the effect of the coating thickness is non-distinctive on the measurement uncertainty.
