Contact-free and fast detection of energetic materials in containments

Abstract The identification of energetic materials in containments is an important challenge for analytical methods the field safety and security. Opening a package without knowledge its contents resulting hazards highly involved with risks should be avoided whenever possible. Therefore, preferable work non-destructive minimal interaction are capable identifying target substances containment quickly reliably. Most spectroscopic find their limits, if substance shielded by covering material. To solve this problem, combined laser drilling method subsequent means Raman measurements through microscopic bore holes material presented. A pulsed beam used both process as excitation source same optical setup. Results show ability new to gain high-quality spectra even when performed small channels. With parameters chosen right, can on sensitive explosives like triacetone triperoxide (TATP). Another advantageous effect arises observed reduction unwanted fluorescence signal spectral data, from confocal-like measurement setup hole acting aperture.
