1. An imaging system comprising:
- a radiation generator that generates a beam of penetrating radiation along a first direction;
an object that receives said beam of radiation, wherein a first beam of radiation is transmitted through said object along said first direction and a second beam of radiation is refracted by said object along a second direction;
a Fabry-Perot analyzer that receives said first and second beams of radiation, said Fabry-Perot analyzer suppresses the intensity of said first beam of radiation and transmits said second beam of radiation; and
a detector system that receives from said analyzer said suppressed first beam of radiation and said transmitted second beam of radiation and generates an image of said object.
