Abstract:
1. An apparatus for detecting radiation incident upon the apparatus, the apparatus comprising: a. a plurality of substantially parallel active collimation vanes sensitive to the radiation, the substantially parallel active collimation vanes enclosed within a light-tight front compartment, for generating an uncollimated detection signal; b. a rear detector, optically isolated from the front compartment, for detecting radiation that passes between the substantially parallel active collimation vanes of the plurality of active collimator vanes and generating a detection signal sensitive to a direction of the radiation incident upon the apparatus; and c. a processor adapted for receiving and processing the uncollimated detection signal into an uncollimated backscatter image and for receiving and processing the detection signal sensitive to a direction of the radiation incident upon the apparatus into a collimated image.
