Analysis of evidence in forensic documents using hyperspectral imaging system

Abstract

Hyperspectral imaging systems provide many images resulting from spectral representations of scanned 2D surfaces. Analysis of questioned documents in forensic investigations can be realized by using hyperspectral imaging techniques. In this study we present the usage of a method, which technically depends on basic theories and approaches is presented in detail. This is realized by our hyperspectral imaging system. This system is used to measure the spectra of 2D surfaces. The tests in this study are conducted using different pens and papers. Satisfactory results are obtained, and interpreted, through the analysis of the obtained data.
