<p>A holographic reflector (20) for reflecting laser radiation at a predetermined wavelength. The reflector employs a plurality of holograms (31, 33) which are disposed adjacent to one another and which are conterminous with each other. The holograms (31, 33) are generally disposed in a support structure (21) which may be a visor or goggle arrangement. Each of the holograms may be either parallel fringe holograms or slanted fringe holograms. The angular orientation of the fringes and the relative spacing thereof determine the angular coverage provided by the reflector (20). The reflector (20) provides for reflection of laser radiation at a predetermined wavelength and within a particular angular subtence (Δυ3,Δυ4,Δυ5) while allowing high see-through in the visible wavelength region. Multiple sets of holograms may also be stacked in order to protect against multiple laser sources.</p> |
