Aerospace thermal mapping applications of liquid crystals.
The ability of liquid crystals to reveal small temperature gradients has resulted in studies of their utility in the thermal testing of aerospace materials and components. Reported here are tests to reveal anomalous conditions at or near the surface of a variety of materials. Also described are low cost techniques for performing thermal mapping on large areas. Advantages and disadvantages of thermal mapping with liquid crystals are summarized.
