TECHNOLOGY DESCRIPTION
The technology is an 8 channels optical interrogator allowing to interrogate an interferometer at the end of the optical fiber (collimated beam). This interrogator is composed of a card powered in 12V. A current modulated diode allows the measurement of displacements with a resolution of 1nm in a frequency band from 0.1 to 50HZ, with a measurement amplitude of several cm. A demodulation software
DEVELOPMENT STAGES
- To date, the technology is at an advanced stage:
- First versions of the electronic board have been developed and new prototypes will be produced, installed and tested in real conditions.
- The software has been implemented and tested on the board's processor, and performance improvements are underway.
COMPETITIVES ADVANTAGES
- 12V/5W/2kg transportable device with possibility of power supply via solar panels- 8 measurement channels
- High-performance integrated software on a wide spectrum of measurement frequencies (0-1kHz)
- Excellent cost / performance ratio
