Mapping or scanning the electromagnetic
emissions of electronic cards or any environment requires the use of
relatively complex mechanical or electronic devices. Being autonomous,
compact and fast, the ScanPhone aims to overcome these constraints. It
makes it possible to map the electromagnetic environment directly on
site or in locations difficult to access, such as inside a vehicle for
example. This scanner, using augmented reality technology for part of
its software, is composed of a smart phone coupled to removable EM field
sensors to allow multiple measuring configurations.

How it works?
Step 1: A detailed
video of the process required for the ScanPhone to display radiation
from a Raspberry
To be able to position a virtual grid
above the equipment under test (EUT), the augmented reality algorithm
implemented in our smartphone computes a large number of reference
points over the surface of the EUT to be scanned. This step is
automatically lanched with our application and last a fews seconds.

Step 2: PRESCAN
Detection of the min and max values
Activation of the prescan function
finds the min and max values over the surface to be scanned. At the end
of the prescan, our module MDMV uses these values in order to optimize
the dynamic output.
