Patent ID: 8666474

Claim:
An inspection device comprising: a biological information measurement unit configured to measure biological information of an inspection target and form an image including the biological information; a magnetic position detector configured to detect a position of the biological information measurement unit and/or the inspection target; a control unit configured to control the biological information measurement unit and the magnetic position detector, the control unit comprising a magnetic-field measurement unit configured to measure strain of a magnetic field in a measurement space in which the biological information measurement unit is placed using an output of the magnetic position detector; and a magnetic-field measurement jig formed by a polyhedron, and has concave portions or marks for engaging a part of a magnetic sensor each one of the concave portions or marks being disposed at a part or all of a plane that forms the polyhedron, wherein the output of the magnetic position detector is positional information corresponding to the concave portions or marks of the plurality of points of a jig affixed in the measurement space, and wherein the magnetic-field measurement unit measures strain of a magnetic field based on the positional information of the detected plurality of points.
