Title
(EN) HANDHELD INDUCTION THERMOGRAPHY SYSTEM
(FR) SYSTÈME THERMOGRAPHIQUE PORTATIF À INDUCTION
Abstract
(EN)
A hand-held thermography system and method for using the hand-held thermography system are provided. The hand-held thermography system includes a housing enclosing components of the thermography, the housing is configured to be hand-held. Within the housing, an electric current generator produces an alternating electrical current, the generator electrically connected to an induction coil. The induction coil is disposed within a slot in a wall of the housing so that the induction coil faces outward from the exterior of the housing. A digital infrared camera, also disposed within the housing, includes a lens having a field of view directed through an opening in the wall enabling it to view the exterior of the housing and capture images such as test objects. A processor connected to the generator controls the electric current and the digital infrared camera and is configured to store the captured images.

L'invention concerne un système thermographique portatif et un procédé d'utilisation du système thermographique portatif. Le système thermographique portatif comprend un boîtier renfermant des composants de la thermographie, le boîtier étant conçu pour être portatif. Dans le boîtier, un générateur de courant électrique produit un courant électrique alternatif, le générateur étant connecté électriquement à une bobine d'induction. La bobine d'induction est disposée à l'intérieur d'une fente dans une paroi du boîtier pour que la bobine d'induction soit tournée vers l'extérieur depuis l'extérieur du boîtier. Une caméra infrarouge numérique, également disposée à l'intérieur du boîtier, comprend une lentille dont un champ de vision est dirigé à travers une ouverture dans la paroi lui permettant de visualiser l'extérieur du boîtier et de capturer des images telles que des objets soumis à essai. Un processeur connecté au générateur commande le courant électrique et la caméra infrarouge numérique et est configuré pour mémoriser les images capturées.
