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
-
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.
