Description

Applications

Some examples of Scanphone mappings with different types of sensor.

Example: mapping low frequency a radiation of a transformer (50 Hz)

Sensor type: G01 (Hall effect sensor)

Bandwidth: 50 – 20000 Hz

Unit: mT

Example: mapping a surface of a electronic card

Sensor type: G02 (Magnetic field)

Bandwidth: 20 kHz – 440 MHz

Unit: dBV

Example: Mapping the radiation of a antenna ( 2 GHz ).

Sensor type: G04 (electric field)

Bandwidth: 300 MHz – 7 GHz

Unit: mV ( sensor output )

Example: Projection of mapping on TV.

With the “broadcast” function of the smartphone, it is possible to project the screen on a compatible TV.
(EasyCast – VDO projector …)

Teaching – Demonstration – Congress …

Example: radiation shielding defect – with spectrum analyzer

Example of mapping a shield fault of an HF cable.

The sensor is here replaced by the detection part of a spectrum analyzer (Selection Fr.Centrale; SweepTime; RBW …; Span Zero Mode). Output option V (y) out.

Example: Planar mapping.

Sensor type: G04 (electric field)

Bandwidth: 300 MHz – 7 GHz

Unit: mV ( sensor output )

Graphic interface

How it works?

Step 1: Construction in augmented reality of the 3D environment.

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.

 

Etape 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.

The sensors

The scanphone is sold with 2 sensors of your choice

(We realize specific sensors on request)

Cooperation

The preliminary studies have been conducted in collaboration with the PIRVI, an engineering unit of the CRIStAL laboratory of the University of Lille, and the support of the IRCICA.
