Abstract:
Apparatus (1) for transilluminating objects (4) which, with the help of a transport device (3), are moved through a transillumination space (5) whereby there are at least first and second radiation sources (10, 20, 30) spaced from one another in a transport direction and at least first, second and third detector apparatus (11, 12, 21, 22, 31) mounted about the transport device (3), each of said detector apparatus being elongated with portions thereof extending about at least two sides of said transillumination space for receiving one of first, second and third ionized beams, wherein:at least each of the first and second ionized beams (FX1.1, FX 1.2, FX2.1, FX2.2, FX3) comes from a different one of said first and second radiation sources (10, 20, 30); said first and second ionized beams intersect one another; one of said first and second ionized beams is at an angle not perpendicular to the transport direction of said transport device; at least said first and second detector apparatus (11, 12, 21, 22, 31) are aligned to receive said first and second ionized beams; and said first and second detector apparatus have portions thereof positioned on opposite sides of said transillumination space crossing one another along said first and second ionized beams (FX1.1, FX1.2, FX2.1, FX2.2, FX3) so that said first and second detector apparatus are interlaced with one another.
