1. An imaging system for analyzing material, comprising:

  • a. a source of penetrating radiation emitting radiation in a direction with respect to an object such as to illuminate a portion of the object up to the entirety thereof;

    b. at least one array of segmented detectors, each array of segmented detectors having a detector axis, for detecting radiation scattered by the object and providing a vector of signals corresponding to the detected radiation;

    c. a mask having a plurality of apertures interposed between the object and the detector array in such a manner that each segmented detector detects radiation scattered through more than one aperture; and

    d. a controller for applying to the vector of signals an operator corresponding to the plurality of apertures in such a manner as to derive an image corresponding to the object.
