New
Hyper-spectrometer Equipment and Software for forensic document
examiners
Forensic Hyperspectrum Document Processor
During
6 years of R&D, original 4D hyper-spectrum data processor
software was developed. Based on Hyper-spectrum image stack
processing the software is optimized for specific document
examining tasks. The program is designed to process data from
Hyper-spectral imaging equipment. It was successfully implemented
in our partner product ForensicXP
automatic full digital hyper-imaging spectrograph. The original
patent pending method was developed for spectral signature
unwrapping and enhancement of spectrometer output. An exceptional
sensitivity of the instrument and broad spectral range permits
to detect very small differences in similar inks.
The software was specifically developed for forensic questioned
document experts. Our
new 4D
hyper-spectrum digital technology proved to reveal the
features not detectable by alternative methods.
ForensicXP spectrometer equipped with our software was exhibited
at 4th Conference of the European Document Experts Working
Group entitled “Digital Technology: the Document Examiner’s
Friend and Foe”. The conference
took place September 27-30, 2006 at the auditorium of the
NFI in The Hague, Netherlands.

Forensic Image Enhancement
3D visualization software was developed to help forensic experts
to see tiny differences in inks and pen pressure as well as
to detect drawing sequence of the lines. Third dimension in
forensic images helps you The 3D forensic image viewer and
analyzer is a valuable tool for questioned document and handwriting
examiners.
