Abstract: A method for detecting neutron radiation in accordance with particular embodiments includes exposing a neutron detector array comprising at least one two-dimensional array of neutron detectors to a first scene of interest. The neutron detector array is based on at least one two-dimensional array of microbolometer detectors. The method also includes receiving a plurality of response values from a corresponding plurality of neutron detectors of the neutron detector array. The method further includes generating a comparison value based on the plurality of response values and a baseline response value. The method additionally, includes determining whether more than a first threshold amount of neutron radiation is being generated by the first scene based on the comparison value.

Abstract: An evacuated testing device (100) including a housing (106) providing a test chamber (101) therein, a first mechanism (102) for retaining an object (116) under test in relation to an aperture (112), a second mechanism (104) positioned within the test chamber (101) for generating and transmitting uniform electromagnetic radiation to the object (116), and a third mechanism (122) disposed within the test chamber (101) in thermal communication with the second mechanism (104) for varying the temperature thereof. In a preferred embodiment, a test dewar (102) and an infrared blackbody radiating source (104) are enclosed within a test chamber (101) of the evacuated testing device (100). A focal plane array (116) is mounted on a cold finger (114) within the test dewar (102) in close proximity to an emissive surface (126) of the blackbody radiating source (104). A thermoelectric cooler (122) varies the temperature of the emissive surface (126) which generates and transmits the infrared radiation.
