Carr, Auteur Année de publication : 1997 Article en page(s) : P. 380-385 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Etude théorique' 'Sphère intégrante' 'Détecteur rayonnement' Photodétecteur 'Fibre optique' Index. décimale : 667.9 Revêtements et enduits Résumé : The integrating sphere is a simple, yet often misunderstood, device for measuring optical radiation. The function of an integrating sphere is to spatially integrate radiant flux. Before one can optimize a sphere design for a particular application, it is important to understand how the integrating sphere works. How light passes through the sphere begins with a discussion of diffuse reflecting surfaces. From this, the radiance of the inner surface of an integrating sphere is derived and two related sphere parameters are discussed, the sphere multiplier and the average reflectance. Finally the time constant of an integrating sphere as presented is relevant to applications involving fast pulsed or short lived radiant energy.

Matériaux intelligentsTags : 'Revêtement intelligent' 'Inhibiteur corrosion' 'Détecteur 'Contrôle Microencapsulation Index. décimale : 667.9 Revêtements et enduits Résumé : Corrosion is a destructive process that often causes failure in metallic components and structures. Protective coatings are the most commonly used method of corrosion control. However, progressively stricter environmental regulations have resulted in the ban of many commercially available corrosion protective coatings due to the harmful effects of their solvents or corrosion inhibitors. This work concerns the development of a multifunctional, smart coating for the autonomous control of corrosion. This coating is being developed to have the inherent ability to detect the chemical changes associated with the onset of corrosion and respond autonomously to control it. The multi-functionality of the coating is based on micro-encapsulation technology specifically designed for corrosion control applications. This design has, in addition to all the advantages of other existing microcapsules designs, the corrosion controlled release function that allows the delivery of corrosion indicators and inhibitors on demand only when and where needed. Corrosion indicators as well as corrosion inhibitors have been incorporated into microcapsules, blended into several paint systems, and tested for corrosion detection and protection efficacy.
