Hyperspectral Imaging Provides Detection and High Contrast Imaging of Biological Stains, According to New White Paper

4 Feb 2015

 

ChemImage announced the release of a white paper discussing the ability of hyperspectral imaging to nondestructively demonstrate sufficient quality images that can assist bloodstain examiners in setting apart biological fluids from substrates. The analysis of biological fluids at a crime scene or on an article of physical evidence can assist investigators in understanding the circumstances surrounding a violent crime as well as provide a link between a suspect, the victim and the crime scene through DNA analysis.

In this proof-of-concept study, scientists at ChemImage used the HSI Examiner™ 1000 instrument, employing visible and near-infrared (NIR) reflectance hyperspectral imaging (HSI), to observe saliva, sweat, urine, blood and semen stains on a variety of natural and semi fabrics. The Examiner's capability for visualizing and presumptively locating the various stains on the different substrates is shown in the results.

The white paper, entitled "Hyperspectral Imaging Provides Detection and High Contrast Imaging of Biological Stains", gives reason to incorporate hyperspectral imaging as a potential solution to some challenges that exist in biological stain analysis.
