Abstract

Système optique pour la lecture de films radiochromiques et procédé de fonctionnement afférent. L’invention concerne un système optique (1) pour la lecture d’un film radiochromique, comprenant : - une source lumineuse (2) comprenant au moins une diode électroluminescente (LED) agencée pour éclairer le film radiochromique, la longueur d’onde d’émission de la diode LED étant adaptée pour correspondre à celle du pic d’absorption maximal du film radiochromique, - une lentille bi-télécentrique (3) agencée pour recevoir le faisceau optique émis par la(les) diode(s) (LED) et ayant traversé le film radiochromique, - un imageur (4) couplé optiquement à la lentille bi-télécentrique. Figure pour l’abrégé : Fig. 1Optical system for reading radiochromic films and method of operation thereof. The invention relates to an optical system (1) for reading a radiochromic film, comprising: - a light source (2) comprising at least one light-emitting diode (LED) arranged to illuminate the radiochromic film, the wavelength d the emission of the LED diode being adapted to correspond to that of the maximum absorption peak of the radiochromic film, - a bi-telecentric lens (3) arranged to receive the optical beam emitted by the diode(s) (LED) and having passed through the radiochromic film, - an imager (4) optically coupled to the bi-telecentric lens. Figure for abstract: Fig. 1
