Magnetovision

Magnetovision is the measuring technique enabling the visualization of magnetic field distribution in a given space.

Measuring setup
Magnetovision measuring stand consists of a magnetometer, X-Y or X-Y-Z movement mechanism and data processing and visualization system. Following modes of magnetovision signal acquisition are possible:


 * magnetometer moves in the measurement area (e.g. over tested object)
 * tested object moves against the magnetometer
 * array of magnetic field sensors is used

Magnetometers
Typically, following types of sensors may be used:


 * magnetoresistance effect based sensors
 * fluxgate magnetometers
 * Hall effect sensors
 * SQUIDs

Types
There are different modes of magnetovision measurements. Measurements may be performed in 2D (X-Y) or 3D (X-Y-Z). Moreover, measurements of magnetic field may be absolute, differential or gradiometric.

Applications
Magnetovision may be used for:


 * nondestructive testing in civil engineering
 * detection of dangerous metallic objects
 * archeology

Data fusion
Magnetovision images may be used for data fusion with visual signal. This creates new possibility of presentation of magnetic field distribution for further analyses.
