METHOD FOR MINE DETECTION AND TENSION BAR FOR ITS REALIZATION Russian patent published in 2007 - IPC F41H11/12 

FIELD: defense sphere, methods for self-detection of mines with tension or teat-off target sensors.

SUBSTANCE: the mine tension bar with a tension or tear-off target sensor is made of material and a surface profile, covered with a temporary coating providing for development of glares on the surface of the tension bar observed at radiation of the tension bar surface after a preset time. For detection of the mine the surface section is illuminated by an artificial or natural light source, and the presence of a mine is indicated by appearance of glares from the light source on the tension bar surface in the form of brighter fluctuations of the reflected light as compared with the background reflection of the illuminated surface section. The surface profile of target sensor tension bar is made in the form of a hologram or a hologram reflection grating, or a construction with a sharp or/and rounded off vertex, or a spherical construction, or, at least, part of a lens, or, at least, part of a phase zonal plate, or, at least, part of the Fresnel lens of a material with a retractive index exceeding the retractive index of the tension bar material at least by 3 per cent.

EFFECT: enhanced efficiency of mine detection and mine clearance of minefields at an enhanced safety of people.
