Research serving society

Measurement is a constant component of our society's activities. It must keep pace with developments springing from advances in science and technology, while meeting ever greater accuracy requirements. This is the main thrust of LNE's fundamental research, upstream of its applied research.

Data storage on digital optical media

Digital optical media : data storage on digital optical media
(CD, DVD,…). A scientific interest group has been formed by LNE, the Laboratoire d'Acoustique Musicale (LAM), the University of Clermont-Ferrand and the French Ministries of Research, Industry and Culture, to create an independent unit for qualification of digital data storage media. Its programme focuses on the performance of CD-Rs, DVD-Rs, DVD±R DLs and DVD±RWs (phase-changing rewritable photosensitive discs) and their interaction with writers, in order to assess their long-term data storage potential. The work includes assessment of optoelectronic parameters and their changes over time, and precise analysis of the chemical properties of photosensitive dyes. Research in this field is important both for private companies and for government departments responsible for preserving the national heritage or storing official data over very long periods.

Road safety

Minimum safety distance in tunnels
[Thomas Lommatzsch]
Drink-driving tests:
development of a new breath test calibration bench.
[Hubert Berry]
Drug screening tests
[Béatrice Lalère]

Transport safety

Fire Safety:
toxic gases emissions
[Eric Guillaume]

[Bernard Picque]

Sustainable development

Air quality:
development of measurement references and methods, particularly for VOCs, PAHs and fine dust particles. This work is carried out by the Central Air Quality Monitoring Laboratory (LCSQA) for the French Ministry of the Environment. LCSQA was set up by LNE with the Ecole des Mines de Douai engineering school and the National Institute for Industrial Environment and Risks (INERIS).

Ground and surface water quality:
development of traceability chains and reference materials for measuring pH and electrical conductivity, detecting pollutants (heavy metals, pesticides) and ensuring pipes comply with health regulations.
[Paola Fisicaro]
Marine pollution:
design and development of remote detection instrumentation for tracking oil pollution. Ongoing projects aim to improve response time when pollution occurs, through automatic integration of geographic data and information relayed by remote detection instruments, real-time transmission of data recorded on land and close to pollution areas, and 24-hour detection capability.
[Sylvain Pierrard]
Greenhouse gases:
development of a method of detecting greenhouse gas leakage from air conditioners, particularly in motor vehicles, in cooperation with the Ecole des Mines de Paris engineering school.
[Pierre OTAL]

Medical / Health

Traceability of measurements in the medical sector:
The areas covered by research in this field include analysis of medicines, in vitro diagnostics, and analyses performed by biomedical laboratories. LNE is contributing to work by the Joint Committee on Traceability in Laboratory Medicine (JCTLM) set up under the aegis of the International Weights and Measures Office BIPM.
[Soraya Amarouche]
Quality of medical examinations:
improved control of equipment used in audiometry, spirometry, blood pressure monitoring, intraocular pressure measurement, etc.
[Soraya Amarouche]
High-frequency aerials, transmitters and receivers:
development of reference equipment for calibration of aerials and studies of transmitters and receivers used in high-frequency telecommunications. This work is intended both to meet the needs of manufacturers and users and to accurately assess the impact of increased electromagnetic radiation on health.
[Lionel Dreux]

Food safety

Active and "smart" food packaging,
studies to assess the potentialities of active antimicrobial packaging for preserving fresh foods; tests of new cleaning and disinfection processes on packaging material, in isolation or in contact with food.
