BODY FLUID DETECTION
Product Development Driven by Ground Breaking Forensic Research
Existing Crime-lite AUTO users can log-in to gain access to a searchable library of more than 18,000 images of body fluids on a wide variety of fabrics, captured using the Crime-lite AUTO under multiple imaging conditions from UV, through the visible spectrum, to IR.
By understanding how body fluids and fabrics interact with high-intensity illumination we can improve our ability to detect this invaluable source of evidence at the crime scene and during laboratory examinations of evidence.
In-situ examination of evidence can save time, money and resources. In-situ multi-spectral photography of evidence can detect valuable traces of DNA. Knowing exactly what to look for, and using pre-set search tools (founded on ground truth data) will benefit any crime scene investigator.
Forensic light sources remain a trusted tool for CSI & laboratory practitioners. Their use enables contrast to be achieved between the forensic trace and the substrate on which it resides. Examiners use high-intensity illumination to reveal traces of evidence including semen, saliva, sweat, urine etc. But, while much is known about the optical properties of the trace, the substrate upon which we are searching is often overlooked.

Ground Truth Data is information that is known to be real or true, provided by direct observation and measurement as opposed to information provided by inference. This empirical evidence facilitates the representative comparison between Ground Truth Data and real-world subject matter, in a scientifically robust and verifiable manner.
Following a recent software update, every Crime-lite AUTO handheld imaging device will include integrated pre-sets generated by the Ground Truth Library – Body Fluid Detection data which (when using the pre-set examination mode) enables the simple, efficient, and effective use of Crime-lite AUTO for the search, detection, and imaging of bodily fluids at the crime scene and in the laboratory.
We believe this data will be of use to anyone seeking to learn more about the detection and visualisation of DNA-yielding body fluids and for the development of advanced search and detection technologies and techniques.
