Abstract
(EN)
The present invention relates to an apparatus for monitoring an inside of a structure, the apparatus comprising: an optical fiber member which is disposed within the structure and from which part of inputted light is side-emitted regardless of a difference in a refractive index between a core and a cladding of an optical fiber, or regardless of an initial incident angle; a color change member in which color change is induced when the color change member is exposed to a predetermined material, and which is disposed as a flexible member such that at least part of the light that is side-emitted from the optical fiber member is absorbed by or penetrates through the color change member; an optical sensor unit for sensing information on the light that has been side-emitted from the optical fiber member and penetrated through the color change member; and a porous protective film which is disposed so as to surround at least part of an outer circumference of the optical sensor unit, and protects the color change member.

La présente invention concerne un appareil pour surveiller l'intérieur d'une structure, l'appareil comprenant : un élément à fibre optique qui est disposé au sein de la structure et à partir duquel une partie de la lumière entrée est émise latéralement indépendamment d'une différence d'indice de réfraction entre un coeur et une gaine d'une fibre optique, ou indépendamment d'un angle incident initial ; un élément à changement de couleur dans lequel un changement de couleur est induit lorsque l'élément à changement de couleur est exposé à un matériau prédéterminé, et qui se présente sous la forme d'un élément flexible de telle sorte qu'au moins une partie de la lumière qui est émise latéralement par l'élément à fibre optique est absorbée par l'élément à changement de couleur ou y pénètre ; une unité capteur optique pour capter des informations sur la lumière qui a été émise latéralement par l'élément à fibre optique et ayant pénétré dans l'élément à changement de couleur ; et un film de protection poreux qui est disposé de manière à entourer au moins une partie d'une circonférence extérieure de l'unité capteur optique, et qui protège l'élément à changement de couleur.
