Patent ID: 7683329

Claim:
System for automatic determination of the density of an object ( 100 ) belonging to a set of objects, characterized in that it comprises: an apparatus ( 2 ) to determine a significant dimension (x) of said object ( 100 ), an apparatus ( 30 ) to determine the intensity (I) of a photon beam attenuated by passing through said object ( 100 ), an acquisition, processing and analysis apparatus ( 200 ), means ( 70 , 72 , 80 , 82 , 84 , 86 , 88 ) of transporting the object ( 100 ) to the apparatus ( 2 ) for determining its significant dimension (x) and towards the apparatus ( 30 ) for determining the attenuated photon intensity, first means ( 74 , 76 , 78 ) of adjusting the position of the object ( 100 ) relative to the apparatus for determining its significant dimension (x), and second means ( 90 , 92 , 94 , 96 , 98 ) of adjusting the position of the object ( 100 ) relative to the apparatus ( 30 ) for determining the attenuated photon intensity, and in that said first and second adjustment means are capable of moving the object ( 100 ) with a precision of the order of one micron with respect to a support plate ( 150 ) on which the elements making up the system are installed, and in that the position of the object ( 100 ) relative to the apparatus ( 30 ) for determining the attenuated intensity (I) is adjusted as a function of the significant dimension (x) of said object ( 100 ).
