Abstract:
1. A detector apparatus for electromagnetic radiation originating from a source, the detector apparatus comprising: a housing; at least one multilayer disposed within the housing, the at least one multilayer defining a leading edge and a trailing edge, wherein the at least one multilayer is adapted to interact with a plurality of high-energy photons within the X-ray portion of the electromagnetic spectrum, impingent from the leading edge, to permit passage of photons of at least one selected from a plurality of different energies; a first securement bracket disposed within the housing, wherein the at least one multilayer is pivotally fixed to the first securement bracket at a position adjacent to the leading edge; a second securement bracket disposed within the housing, wherein the at least one multilayer is adjustably supported by the second securement bracket at a position adjacent to the trailing edge; at least one detector disposed adjacent to the trailing edge of the at least one multilayer, wherein the detector is adapted to detect the impingent high-energy photons after interaction with the at least one multilayer; and at least one adjustment mechanism operatively connected to the second securement bracket, wherein the at least one adjustment mechanism adjusts the position of the second securement bracket to alter an angular position of the at least one multilayer wherein the at least one multilayer is oriented along a radial line extending outwardly from the source.
