Abstract: A tunnel computerised tomographic scanner comprising a rotor (3), an X-ray emitter (7) mounted on the rotor (3), an X-ray detector (8) mounted on the rotor (3), on the opposite side of a detecting zone (4), the X-ray detector (8) comprising a scintillator (9) which has at least one emission face (10) from which the scintillator (9) emits light in the visible spectrum when it is struck by X-rays, and a plurality of video cameras (12) which are positioned in such a way that each of them frames at least one portion of the scintillator (9), for acquiring one after another second images, in the visible spectrum, of the respective portion of the scintillator (9), wherein, according to the method, at least two separate video cameras (12) substantially frame each zone of the emission face (10), and an electronic processing unit is programmed to combine all of the second images obtained by the video cameras (12) and to obtain a first image of the emission face (10), to be used for the tomographic reconstruction of an object (6) which is placed in the detecting zone (4).

Abstract: This disclosure relates to a method for non-destructive inspection of a fruit (1) having an axis of rotational symmetry (10). The method comprises the step of positioning the fruit (1) in such a way that its axis of rotational symmetry (10) has an orientation that is substantially parallel to a predetermined plane (20) and the step of radiographing the fruit (1), where the direction of emission of X-rays is substantially perpendicular to said predetermined plane (20) and an X-ray image obtained (41) lies on said predetermined plane (20). The X-ray image obtained (41) is processed to calculate, at corresponding points of the X-ray image (41), respective values of attenuation of the X-ray signal through the fruit (1). The X-ray image (41) is divided into a plurality of sections (415) which are perpendicular to the projection (410) of the axis of rotational symmetry (10) on the predetermined plane (20). Each section (415) is the projection of a corresponding slice of the fruit (1) that is substantially perpendicular to the axis of rotational symmetry (10). For each section (415), the deviation between a signal attenuation trend obtained from processing the X-ray image and a reference trend, or the deviation between a trend of a local coefficient of average attenuation obtained from processing the X-ray image and a trend with constant value, is examined in order to identify any anomalies, discontinuities or variations which are indicative of respective non-uniformities in the corresponding slice of fruit. This disclosure also relates to an apparatus (9) for carrying out a non-destructive inspection of a fruit (1) having an axis of rotational symmetry (10), said apparatus being configured for implementing the method according to the disclosure.

Abstract: Method and apparatus for capturing an image of a lateral face of a wooden board, where the lateral face (2) is parallel to a main axis of development of the wooden board (3), with the method comprising a step for feeding the wooden board (3) with the lateral face (2) transverse to a feeding direction (4), a step for illuminating the lateral face (2), a step for capturing, using a plurality of area scan cameras (9), a plurality of first digital images at different times, where each first digital image comprises a portion (10) of the lateral face (2) extending for an entire height of the lateral face (2) transverse to the main axis of development and for part of a length of the lateral face (2) along the main axis of development, where the set of all such portions (10) corresponds to the entire lateral face (2), and a merging step for merging the first digital images using an electronic processing unit to obtain a second digital image showing the entire lateral face (2).
