DLT (Differential luminescence thermometry)
by: Aram Gragossian
Is a non-contact spectroscopic technique to measure the temperature change of glasses and crystals with high precision. By comparing the luminescence to a reference DLT calculates the temperature. All you need is to measure luminescence of your crystal at different temperatures once. for more details refer to “Optical Refrigeration: Science and Applications of Laser Cooling of Solids” and “Differential luminescence thermometry in laser cooling of solids.” To run this program you need Ocean Optics Spectrometer Support from Instrument Control Toolbox. Download the package from Mathworks.
