Real Time Visualization of Radio Waves

Luxondes imagines, develops and manufactures, real-time measurement and visualization tools for electromagnetic fields, making the scientific message accessible around the treatment and analysis of electromagnetic waves

Born from the ambition of two passionate experts in physics and innovation, Luxondes imagines, develops and manufactures realistic measurement and visualization tools for electromagnetic fields. These real-time visualization tools convert electromagnetic waves into visible color information in a chromatic range that varies according to their intensity. Destined for the worlds of industry, research and education, Luxondes’ solutions are designed to make electromagnetic wave processing and analysis accessible.

The study and the realization of the different systems presented by Luxondes are the fruit of a close collaboration with the LEOST/COSYS laboratory of the Gustave Eiffel University.

Technology – MDMV ™ Conversion
LUXONDES MDMV (Maximum Dynamics for Minimum Variations) technology
MDMV (Maximum Dynamics for Minimum Variations) technology is entirely analog, which allows an almost real-time response of the system.

Conversion module
Conversion module Our different visualization systems (2D / 3D) consist of modules that directly convert the RF field level into color levels emitted by an RGB LED via an adaptation interface.

MDMV ™ Module
Our MDMV ™ analog system always maintains the maximum dynamic regardless of the difference in voltage between the high and low thresholds defined by the system or the user.

LUXONDES SCANPHONE

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.

https://www.youtube.com/watch?v=u3ycS62gneE&t=50s

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.
