“…To demonstrate the potential of HSI in forensic investigations, Payne et al compared HSI to point measurements performed with traditional spectrometers [49]. They used Vis/NIR HSI to differentiate between a set of tapes and adhesives, a set of inks ( Figure 10) and two brands of firearm propellants, based on reflectance and photoluminescence properties.…”

Hyperspectral imaging (HSI) integrates conventional imaging and spectroscopy, to obtain both spatial and spectral information from a specimen. This technique enables investigators to analyze the chemical composition of traces and simultaneously visualize their spatial distribution. HSI offers significant potential for the detection, visualization, identification and age estimation of forensic traces. The rapid, non-destructive and non-contact features of HSI mark its suitability as an analytical tool for forensic science. This paper provides an overview of the principles, instrumentation and analytical techniques involved in hyperspectral imaging. We describe recent advances in HSI technology motivating forensic science applications, e.g. the development of portable and fast image acquisition systems. Reported forensic science applications are reviewed. Challenges are addressed, such as the analysis of traces on backgrounds encountered in casework, concluded by a summary of possible future applications.

“…In the same paper photoluminescence spectra of two multi-layered paint specimens were compared using HSI [49]. Because both spectral and spatial data were gathered, differences in paint layers could easily be highlighted visually, as an alternative to a spectral comparison.…”

“…Payne et al [18] published a paper showing preliminaries results of ink analysis using UV-vis, vis-NIR and fluorescence chemical images to analyze different brands of pens. Specifically in the vis-NIR range, the authors analyzed only blue ballpoint pen inks using the PCA of hyperspectral images to discriminate among different brands of 9 blue ballpoint pens purchased.…”

“…Digital colour imaging has been used to successfully correlate the state of parchment aging and deterioration with visible (red, green, blue) reflectance [19]. Forensic scientists have also explored the use of visible and IR imaging for distinguishing inks in fraudulent documents and currency [20]. Brauns and Dyer [21] used a hyperspectral visible imaging system for examining red, blue and black inks.…”
