SENSOR TAG MULTIPLANE IMAGING SYSTEM

摘要

When a conventional sensor and a tag is sandwiched by a plurality of metal planes, the condition is degraded and the sensitivity is lowered. Provided is multiplane imaging system using MISEMAS (Multi-Image Effect and Separation Method for Magnetic Sensor and Tag) in which the sensitivity is not lowered but rather enhanced and it is possible to separate and select each of the tags without causing interference between adjacent sensors, tags SC₁, SC₂, SC₃, SC₄, or R₁, R₂, R₃, R₄, thereby enabling an effective use of metal surface current and a magnetic path.
