Abstract : Cholesteric liquid crystals, because they exhibit predictable temperature-dependent color changes, are a valuable indicator for qualitative and quantitative thermal analysis, particularly the observation of varying thermal phenomena over continuous surfaces. The report describes the properties of liquid crystals, applications, and a demonstrative experiment in which liquid crystals were used to observe transient and equilibrium thermal patterns of AN/SQS-26 transducers.
