title = "A transient technique for calibrating thermochromic liquid crsytals: The effects of surface preparation, lighting and overheat",
abstract = "This paper describes a transient technique for thermochromic liquid crystal hue-temperature calibration and presents results on the effects of surface preparation, lighting and overheat on that calibration. An image acquisition system and calibration test plate were designed for transient measurement and are described. The transient calibration results compare well to steady state calibration results for cooling and heating rates of 0.03 °C/s. Hysteresis occurred when the surface was heated above the play range of the crystals but was not permanent. We found that a poorly prepared liquid crystal surface yielded a {"}steep{"} calibration curve, was subject to light 'warm up' effects and the hysteresis effect was severe upon overheating.",
