Method and system for detecting neutron radiation

A method for detecting neutron radiation, comprising:

• 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 based on at least one two-dimensional array of microbolometer detectors;
• receiving a plurality of response values from a corresponding plurality of neutron detectors of the neutron detector array;
• generating a comparison value based on the plurality of response values and a baseline response value;
• and
• determining whether more than a first threshold amount of neutron radiation is being generated by the first scene based on the comparison value.

A system for detecting neutron radiation, comprising:

• a neutron detector array comprising at least one two-dimensional array of neutron detectors based on at least one two-dimensional array of microbolometer detectors, the neutron detector array configured to be exposed to a first scene;
• a readout circuit coupled to the neutron detector array, the readout circuit configured to generate a plurality of response values from a corresponding plurality of neutron detectors of the neutron detector array;
• and
• a processor coupled to the readout circuit, the processor configured to:
• generate a comparison value based on the plurality of response values and a baseline response value;
• and
• determine whether more than a first threshold amount of neutron radiation is being generated by the first scene based on the comparison value.

One or more computer-readable non-transitory storage media embodying software that when executed by a processor is configured to:

• expose a neutron detector array comprising at least one two-dimensional array of neutron detectors to a first scene of interest, the neutron detector array based on at least one two-dimensional array of microbolometer detectors;
• receive a plurality of response values from a corresponding plurality of neutron detectors of the neutron detector array;
• generate a comparison value based on the plurality of response values and a baseline response value;
• and
• determine whether more than a first threshold amount of neutron radiation is being generated by the first scene based on the comparison value.
