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
tested object moves against the magnetometer
array of magnetic field sensors is used

Magnetometers

Typically, following types of sensors may be used:

Types

There are different modes of magnetovision measurements. Measurements may be performed in 2D or 3D. 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.
