Magnetovision
# 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.
