Identification of Heroin Covered by Simulation Skin Using Energy Dispersive X-ray Diffraction and Coherence Function

An inspection technique based on energy dispersive X-ray diffraction (EDXRD) has been developed to provide chemically specific detection of samples. Implementing this technique and coupling with appropriate analysis algorithm provide specific material identification. Profile analysis has been performed using the Coherence Function. The Results suggest that it is feasible to recognize heroin covered by simulation skin through coherence function analysis method. Meanwhile, the coherence coefficient can also be made as criterion of characteristic signal recognization. Thus, heroin in the body may be identified automatically through this kind of technique.
