Abstract: The present invention relates to an Apparatus for inspection of concave elements, for detection of contaminations and/or defects, comprising means for lighting a concave element to be subjected to inspection, an image detection unit, such as a camera or like, an optic group and means for processing images acquired by said image detection unit, in order to individuate said contaminations and/or said defects of said concave element, characterized in that said lighting means comprise a first light source, suitable to generate a diffused lighting direct on the concave surface, and a second light source, suitable to generate a grazing lighting directed on the outer lateral surface of said concave element, and in that said optic group is placed so as to detect light emitted by concave surface and transmitting the same to said image detection unit.

Abstract: A method comprises projecting a light and shade pattern defined by preset optic parameters through a body, detecting an image of the light and shade pattern through the body to obtain a detected image, processing the detected image to highlight any irregularities of the light and shade pattern in the detected image; an apparatus comprises a light-source for projecting a light and shade pattern defined by preset optic parameters through a body, an image-detecting device for detecting an image of the light and shade pattern through the body to obtain a detected image and a processing device for processing the detected image in such a way as to highlight any irregularities of the light and shade pattern in the detected image.
