Mine with search and detect sensor - has adjustable mirror for energy-efficient search cone adjustment

摘要

Mine has a sensor arrangement (12) for emitting a search beam (14) and for receiving its reflection from a target, partic. at depth. The arrangement includes a mirror (30) for deflecting the search beam, with a drive (32) to deflect the beam through a cone by rotation about an axis (34) intersecting the mirror. An articulated joint (36) connected the mirror to the axis allows the mirror to be pivoted to adjust the cone angle. ADVANTAGE - Energy consumotion in the search phase is minimal.
