Résumé

A technique is described for measuring the two dimensional distribution of temperature over a relatively large surface in a laboratory experiment. The technique uses a phosphor coating on the surface which is illuminated locally with ultra-violet light. The phosphor then emits visible light, the intensity of which is dependent on the surface temperature. By calibrating the system, the measured light output from a small area can be used to indicate the local surface temperature. If carried out with care the technique is accurate to about 1°C.
