Abstract: A counter measure apparatus and method for modifying a path of an electromagnetic detector signal (204) so as to prevent incidence thereof on a platform (200), the apparatus comprising an electromagnetic radiation source, communicably coupled to a control system. The control system is configured to create an atmospheric element (202) operative to simulate a physical electromagnetic radiation path modifying device within an atmospheric volume located in said electromagnetic detector signal path (204) by causing electromagnetic radiation from the source to be applied to a selected plurality of three-dimensional portions of said atmospheric volume so as to heat and/or ionise the air within said portions, wherein said selected portions are spatially located together in a substantially unbroken, three-dimensional configuration.

Abstract: Apparatus and method are disclosed for co-aligning laterally displaced radiation beams from respective radiation source outputs, each beam comprising a number of spectral components. The apparatus comprises a collimating element for receiving each of said radiation beams with respective lateral displacements and a combining element for receiving each of said radiation beams passed by said collimating element for co-aligning the radiation beams. The apparatus further comprises a diffraction assembly disposed in an optical path between the output of at least one radiation source and the collimating element, for spatially separating the radiation beam output by said at least one radiation source into the constituent spectral components of radiation prior to passing the radiation to the collimating element.

Abstract: A directed-energy weapon counter measure apparatus and method for modifying a path of a focused electromagnetic energy beam (204) emitted by a directed energy weapon system so as to deflect it from a platform (200), the apparatus comprising an electromagnetic radiation source, communicably coupled to a control system. The control system is configured to create an atmospheric element (202) operative to simulate a physical electromagnetic radiation path modifying device within an atmospheric volume located in the path of the focused electromagnetic radiation beam (204) by causing electromagnetic radiation from the source to be applied to a selected plurality of three-dimensional portions of said atmospheric volume so as to heat and/or ionise the air with in said portions, wherein said selected portions are spatially located together in a substantially unbroken, three-dimensional configuration.
