Abstract

El aparato (1) para verificar neumáticos que comprende una cámara lineal (5) que tiene una línea del objetivo (106) que se encuentra en un plano óptico (107); una primera (108), una segunda (109) y una tercera (110) fuente de luz, para emitir respectivamente una primera, una segunda y una tercera radiación de luz; una unidad de mando y control (140) para accionar selectivamente por lo menos una de entre la primera, la segunda y la tercera fuente de luz y activar la cámara lineal a fin de adquirir una imagen bidimensional de una porción de superficie (201) lineal del neumático sincrónicamente con la activación de la primera, la segunda y la tercera fuente, en donde la primera y la segunda fuente de luz residen en lados opuestos del plano óptico, en donde la primera, la segunda y la tercera fuente de luz comprenden cada una o más unidades secundarias (111, 112, 113) cada una con una respectiva dirección de extensión principal (114) paralela al plano óptico y en donde la distancia de las fuentes secundarias de la tercera fuente de luz desde el plano óptico es menor que las distancias de la primera y la segunda fuentes de luz del plano óptico.
