Based on comprehensive analysis of thermochromic liquid crystal measurement methods

insight into the main influential factors to any general calibration was provided.The relative position of the strobe and camera and the distance of these two devices to the shooting window were kept

and the temperature difference from the shooting modes with and without shooting window

the thickness of plexiglass shooting window

the differences between cooling or heating cycles (hysteresis) and the number of heating or cooling cycles (aging) are up to 0.5℃

0.2℃

0.26℃ and 1.2℃

respectively;the sealing gap of rotor-stator disc does not affect the performance of the thermochromic liquid crystal;the relationship of temperature and hue depends on the light-emitting medium.
