Title (EN) APPARATUS FOR ACQUIRING IMAGES OF ELEMENTS TO BE INSPECTED AND METHOD OF INSPECTIONS OF SUCH ELEMENTS
(FR) APPAREIL PERMETTANT D'ACQUÉRIR DES IMAGES D'ÉLÉMENTS À INSPECTER ET PROCÉDÉ D'INSPECTION DE TELS ÉLÉMENTS
Abstract: front page image
(EN)There is described an apparatus for obtaining images of an element (50) to be inspected, comprising first acquisition means (1 1 ) and second screening means (22) which can be activated according to a first activation mode, and deactivated according to a first deactivation mode; second acquisition means (21 ) and first screening means (12) which can be activated according to a second activation mode, and deactivated according to a second deactivation mode; the first acquisition means (1 1 ), the first screening means (12), the second acquisition means (21 ) and the second screening means (22) aligned along a common optical axis (100); wherein said first activation and deactivation mode and said second activation and deactivation mode occur in a predetermined sequence in order to obtain images of the first side (51 ) and of the second side (52) of the element (50), wherein said first screening means (12) and said second screening means (22) include an optical device (17), respectively, in turn containing a plate-like body (13) provided with colorless and light-diffusing impurities, said impurities adapted to modify the optical path of an input light beam which crosses said plate-like body (13), said plate-like body (13) also operatively coupled to at least one LED (120, 121, 122, 123).
(FR)L'invention concerne un appareil permettant d'obtenir des images d'un élément (50) à inspecter, comprenant des premiers moyens d'acquisition (11) et des seconds moyens de tri (22) qui peuvent être activés en fonction d'un premier mode d'activation, et désactivés en fonction d'un premier mode de désactivation ; des seconds moyens d'acquisition (21) et des premiers moyens de tri (12) qui peuvent être activés en fonction d'un second mode d'activation, et désactivés en fonction d'un second mode de désactivation ; les premiers moyens d'acquisition (11), les premiers moyens de tri (12), les seconds moyens d'acquisition (21) et les seconds moyens de tri (22) sont alignés le long d'un axe optique (100) commun ; ledit premier mode d'activation et de désactivation et ledit second mode d'activation et de désactivation se produisant dans une séquence prédéfinie afin d'obtenir des images du premier côté (51) et du second côté (52) de l'élément (50), lesdits premiers moyens de tri (12) et lesdits seconds moyens de tri (22) comprenant un dispositif optique (17), respectivement, contenant tour à tour un corps en forme de plaque (13) doté d'impuretés incolores et diffusant la lumière, lesdites impuretés étant conçues pour modifier le trajet optique d'un faisceau de lumière d'entrée qui traverse ledit corps en forme de plaque (13), ledit corps en forme de plaque (13) étant également couplé fonctionnellement à au moins une DEL (120, 121, 122, 123).
