Aplicación STANDOFF LIBS: Detección de explosivos
Hola chicos! Al hilo de lo visto en clase de en lo referente a la técnica STANDOFF LIIBS os dejo información acerca de una aplicación con un montaje similar al visto en la asignatura. En este caso utilizan esta técnica para la detección de explosivos.
Stand-off techniques have received increasing attention as valuable methods for material analysis at remote distances. This is particularly relevant when looking at hazardous contaminants in the environment or residual explosive material, where it is desirable for the analyst to remain at a safe distance from the material being investigated.
The ability to detect dangerous contaminants, improvised explosives(IED), home made explosives (HME), or nuclear by-products, has become of increasing importance due to heightened risks in recent decades. In their work, Gonzalez and co-workers set out to test the feasibility of making such measurements with their TELELIBS sensor, and to assess the influences that the barrier position and its composition might have on the quality of those measurements. In allied work the group looked at the influence of atmospheric turbulence on beam propagation to and from the target [2], where they showed that measurements over several tens of meters could be significantly affected by atmospheric turbulence.
More recently the group have demonstrated the simultaneous use of both stand-off LIBS/stand-off Raman to analyse such materials.
