Alison sensor - Identification of explosive substances and precursors by Raman and LIF spectroscopic techniques
The NUC-TECFIS-DIM Laboratory is committed to the development of increasingly compact and efficient non-destructive and non-invasive (or micro-destructive) laser systems, based on Laser Induced Fluorescent (LIF), Raman Spectroscopy, for the characterization of even fragile materials in the laboratory and in situ, even in hostile environments, without the need for sampling or treatment of the target, using only the optical accessory on the surface, and measuring the distance.
Application sectors
Problem to solve
It is often necessary to be able to characterize materials without sampling, in a non-invasive and non-destructive way, in real time or near real time. These needs can be coupled with the need to work at a distance (up to tens of meters) from the targets of interest.
Description
The sensor is an innovative device designed to quickly identify traces of chemical substances at a crime scene without damaging the samples, or in the security field. Its operation is based on Raman spectroscopy and Laser-Induced Fluorescence techniques. When combined, these two methods allow for a detailed analysis of the molecular structure of substances. For this reason, they are integrated into the same instrument, working together to provide more reliable results. The device is designed to be easily transportable, thanks to a convenient trolley with a built-in battery that allows it to operate for several hours without needing a power outlet. This makes it particularly useful for outdoor environments or situations where direct power supply is not available.
