Claim 12:
13. A device for acquiring spectra of radiation transmitted by an object, comprising:
a radiation source configured to emit incident ionizing electromagnetic radiation toward the object;
a detector comprising pixels, each pixel being configured to detect ionizing electromagnetic radiation transmitted by the object to the detector, and to acquire an energy spectrum thereof;
a mask, configured to be interposed between the radiation source and the object, the mask comprising absorbent elements, the absorbent elements being configured to absorb a portion of the incident ionizing electromagnetic radiation, and a projection of the absorbent elements onto the detector defining shadow regions that are distant from one another; and
a processor, configured to receive the energy spectrum acquired by each pixel, and to implement b) to f) of the method of claim 1.
