ABSTRACT:
1. An infra-red detector unit adapted to be mounted on a projectile comprng a nose adaptor having at least one aperture therein, an open "O" unit mounted in said nose adaptor and having at least one aperture that is correlated with the aperture in said nose adaptor, insert means having first and second slit apertures substantially filling the aperture in said "O" unit, a reflector comprising a plurality of strips mounted in said "O" unit and having a parabolic curved surface with a first and second focal point for reflecting infra-red rays from a target source as they pass through said first and second slit apertures, first and second infra-red detecting cells mounted at the first and second focal points of said reflector, said infra-red rays passing through said first and second slit apertures and reflected by said reflector onto said first and second detecting cells thereby providing a first channel for said first infra-red detecting cell and a second channel for said second infra-red detecting cell whereby when the infra-red rays pass through the first and second channels in rapid succession during the flight of the projectile a detonating signal is generated.
