Analysis of double-diffusive convection during crystallization using a simultaneous measurement of temperature and concentration fields

For the purpose of development of techniques obtaining the temperature field, the visualization of temperature field in a liquid phase using LIF was performed. Through the analysis of the tristimulus values (RGB) of the fluorescence image, it was found that the change in the brightness of red is linear with temperature and depends on output power of laser. The quantification of LIF images become possible by using these relations.
