Proximity fuze and projectile equipped with a proximity fuze of this type

摘要

Proximity fuze suitable for equipping a projectile, said fuze having the mission of detecting an obstacle (2) in the vicinity, an obstacle in the proximity being defined as being an obstacle that has a minimum distance to said fuze, including said fuze (30 ) at least: - an emission device (51, 33) having an emission pupil (33) that emits a light beam (31) towards the front part of said fuse; - a reception device (52, 34) having a reception pupil (34) that detects the luminous fluxes in a reception cone (32) towards the front of said fuse, said light beam and said reception cone having some relative orientations such that they intersect, the emission pupil (31) and the receiving pupil (32) being eccentric; a detection volume (35) being the volume where said light beam crosses said cone, so that when an obstacle is in said detection volume, the light emitted by said emission device is backscattered towards said detection device, being an obstacle in the proximity detected by the detection of the maximum backscattered power (62, 72), characterized in that said reception cone (32) is centered on the axis (40) of said fuse.
