1. A detector for detecting thermal radiation in multiple coverage zones, said detector comprising:

  • a support structure;

    a first thermal detection sensor coupled to the support structure and arranged to detect thermal energy in a first coverage zone;

    a second thermal detection sensor coupled to the support structure for detecting thermal energy in a second coverage zone; and

    an optical lens coupled to the support structure and arranged to direct thermal energy from the first coverage zone to the first thermal detection sensor and to direct thermal energy from the second coverage zone to the second thermal detection sensor.
