Abstract
Official abstract text for this publication.
Disclosed herein is a magnetic field measurement device that includes a first sensor unit having one or more magnetic sensors, a second sensor unit having one or more magnetic sensors and one or more magnetic field generating coils, and a moving mechanism configured to change a relative positional relationship between the first and second sensor units.
First claim
Opening claim text (preview).
What is claimed is: 1 . A magnetic field measurement device comprising: a first sensor unit having one or more magnetic sensors; a second sensor unit having one or more magnetic sensors and one or more magnetic field generating coils; and a moving mechanism configured to change a relative positional relationship between the first and second sensor units. 2 . The magnetic field measurement device as claimed in claim 1 , wherein the first sensor unit includes a plurality of the magnetic sensors with fixed relative positional relationship, and wherein the second sensor unit includes a plurality of the magnetic sensors with fixed relative positional relationship. 3 . The magnetic field measurement device as claimed in claim 2 , wherein the second sensor unit includes a plurality of the magnetic field generating coils with fixed relative positional relationship, and wherein the plurality of magnetic sensors included in the second sensor unit and the plurality of magnetic field generating coils included in the second sensor unit have fixed relative positional relationship. 4 . The magnetic field measurement device as claimed in claim 3 , wherein the moving mechanism is configured to change a distance and an angle between the first and second sensor units. 5 . The magnetic field measurement device as claimed in claim 1 , wherein the magnetic field generating coil is disposed at a position not protruding from a sensor head included in the second sensor unit in a direction toward the first sensor unit.
