International audience; Non-contact temperature measurement in a nuclear reactor is still a huge challenge because of the numerous constraints to consider, such as the high temperature, the steam atmosphere, and irradiation. A device is currently dev

The temperature of a transparent Cd 0.7 Sr 0.3 F 2 : Er 3+ (4%)–Yb 3+ (6%) crystalline plate 0.3 mm thick heated by a near-infrared (974 nm) laser diode and probed by a red (652 nm) laser was accurately evaluated as a function of the infrared power

We have determined the temperature into the bulk of a transparent material excited by a red dye tunable laser thanks to a nondestructive method using the green fluorescence emitted by the Er3+ ions incorporated in the material. A homemade Er3+-doped

A device for non-intrusive temperature measurements of metallic materials has been developed. Moreover, as the emissive properties of the metal cannot be known a priori, multiwavelength pyrometry was used to address this issue in the following way:

The object of this work is to approach the possibilities of stimulated infrared thermography for in situ measurement of thermal diffusivity of mural paintings of the inheritance. We present first the principle of the method. We show then the feasibil
