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 dazzler arrangement is described in which the strength of the dazzle beam (11) is modulated in accordance with the range of a target to be dazzled. A stray detection beam (29) is transmitted alongside the dazzle beam (11) to allow detection of a secondary object approaching or at the periphery of the dazzle beam (11), whereupon the dazzle beam (11) is attenuated or inhibited. The dazzler arrangement may include a rangefinder (18).

Abstract: Apparatus for co-aligning a plurality of laterally displaced radiation beams, each beam comprising a respective waveband, is disclosed. 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 to cause the radiation beams to become co-aligned. At least one of the collimating element and the combining element comprises an anti-reflection layer for minimising reflection of the radiation beams from the at least one element. The layer comprises an array of microstructured protuberances which extend away from at least a portion of a surface of the respective element, and which comprise a cross- sectional area which reduces along the length thereof, from a proximal end of the protuberance disposed proximate the surface to a distal end of the protuberance.

Abstract: A method of combining and co-aligning a plurality of radiation beams each having a respective waveband, includes the steps of passing each of said radiation beams to a respective lateral deflector to impart a selected lateral displacement to said beam. Each of said radiation beams with respective imparted lateral displacements is then passed to an optical collimating element which passes said radiation beams to an optical deflecting element which applies a wavelength dependent deflection to the radiation beams. The respective lateral displacements are selected having regard to the waveband of each beam to cause all to exit the optical deflecting element at the same angle so they are co-aligned. An apparatus for carrying out the method is presented. Additionally, an apparatus and method for separation of an input field of radiation containing a plurality of wavebands are presented; the apparatus includes an optical deflector, a focussing element and a plurality of lateral deflectors. Further, an apparatus and method for beam steering are presented; the apparatus includes a lateral deflector and a collimating element. An apparatus and method for angularly deflecting a detection beam are presented; the apparatus comprises a focussing element and a lateral deflector.

Abstract: Co-aligning a number of laterally displaced radiation beams 11a-c from radiation source outputs 12a-c, such as lasers, each beam 11a-c having a respective waveband. An apparatus 10 has a collimating element 13, such as a lens, for receiving each of the beams 11a-c with respective lateral displacements and a combining element 14, such as a diffraction grating or prism, for receiving each of the beams 11a-c passed by the collimator 13. A radiation source mount 15 positions the radiation sources 12a-c relative to the collimator 13 and the longitudinal position of the radiation sources 12a-c upon the mount 15, relative to the collimator 13, is determined in dependence upon the waveband of each beam 11a-c, to cause the beams 11a-c passed by the combiner 14 to be co-aligned.

Abstract: An optical surface roughness measurement-enabling arrangement and method are disclosed for enabling measurement of the surface roughness of a material. The arrangement comprises an optical radiation source for generating a beam of collimated radiation along a first axis for illuminating the surface of the material with the radiation directed along the first axis, a refractive optical element optically alignable with the beam of radiation for refracting the beam along a second axis which is non-parallel with the first axis, for illuminating the surface of the material with the radiation directed along the second axis and a detector which is arranged to detect the radiation, incident upon the surface along the first axis and second axis, which becomes reflected off the surface of the material. An optical surface roughness measuring arrangement and method are also disclosed for providing a measurement value of the surface roughness.

Abstract: Co-aligning a plurality of radiation beams 10 each having a respective waveband is achieved by passing the beams 10 to respective lateral deflectors 12 to impart a selected lateral displacement, then passing the beams to an optical collimating element 14 and then passing the beams to an optical deflecting element 16 which applies a wavelength dependent deflection to the radiation beams. The respective lateral displacements are selected having regard to the waveband of each beam to cause all to exit the optical deflecting element at the same angle so they are co-aligned 18. Other inventions relate to separating a single beam into multiple beams of different wavelength (fig 9), and to deflecting or guiding beams using deflectors to/from collimators/focusers.
