Last week

We looked at a cancer patient in Singapore who was detained by U.S. customs because his medication made his fingerprints unreadable.

This week

We look at recent commercial improvements in hyperspectral imaging related to latent print analysis.


Hyperspectral Imaging for Latent Print Analysis

 All information from:

ChemImage’s CONDOR™ Hyperspectral Imaging System utilizes liquid crystal-based technology for superior visualization of latent prints in comparison to conventional methods. This technology makes possible the improved visualization of fingerprint ridge detail, especially on complex, patterned or otherwise interfering backgrounds.

It Provides:

  • -  Superior detection and contrast enhancement capabilities
  • -  A spectrum associated with each pixel in the image
  • -  Optimized image contrast against complex backgrounds
  • -  Rapid data acquisition
  • -  Nondestructive analysis
  • -  Accurate, reliable, validated, courtroom-friendly results
  • -  Visible, near infrared (NIR) and fluorescence imaging
  • -  Preservation of evidence that allows for additional sample analysis
  • -  A highly configurable system for individual experimental needs
  • -  Reduced possibility of contamination
  • -  Courtroom-friendly results

Images captured through traditional analysis are collected at one specific color, with a single barrier filter. With hyperspectral imaging, the use of a liquid crystal-based technology eliminates the need for all barrier filters. By combining standard digital imaging techniques with common spectroscopic methods, our technology provides increased sensitivity and enhanced fingerprint-to-substrate contrast.



Pittsburgh, PA (ChemImage Corporation) June 3rd, 2009 – Scientists at ChemImage are pleased to report significant improvements in the ability to enhance contrast of untreated fingerprints on paper substrates. Using the CONDOR™ Hyperspectral Imaging System, application scientists at ChemImage have been able to apply new developments in software and hardware configurations resulting in the enhancement of more ridge detail of untreated latent prints on paper.

“The results are very promising,” said John Belechak, Chief Operating Officer at ChemImage, “To compare the images of these untreated fingerprints to those that we’ve seen in previous publications demonstrates a noteworthy step forward in the science of latent print examination.”

The CONDOR Hyperspectral Imaging System utilizes liquid crystal imaging technology, which provides fingerprint examiners with the ability to nondestructively enhance contrast between the print residue and the substrate. When combined with the powerful ChemImage Xpert™ software package, users have access to a significant number of image filtering algorithms. This software becomes extremely important when examining fingerprints on dark substrates or substrates with complex backgrounds.

“While our CONDOR Hyperspectral Imaging System can be used to compliment many processing techniques for fingerprints, it can also provide a means of examining untreated prints, especially if the evidence may contain DNA or includes sensitive documents or art,” said Belechak.

The CONDOR™ - fast, accurate, hyperspectral imaging for forensics applications

The CONDOR Hyperspectral Imaging System applies ChemImage’s hyperspectral imaging techniques—in tandem with our proprietary ChemImage Xpert™ software—to the study of a wide variety of forensic samples to reveal information that cannot be obtained using conventional techniques.

For Forensic Examiners, Scientists and Laboratory Technicians…

The CONDOR provides superior discrimination capabilities than any other forensic imaging instrumentation on the market today. The CONDOR can be used to examine questioned documents, latent prints, trace and bloodstain evidence in a fast, nondestructive manner. Through our unique image presentation resources the CONDOR’s results can translate easily to courtroom testimony.

Q: What is the size of the CONDOR?
A: For laboratory use only, the CONDOR is 1.75 ft (.53 m) deep x 2.25 ft (.67 m) wide x 4 ft (1.22 m) tall

Q: What agencies/laboratories currently use the CONDOR?
A: The CONDOR is currently in use at the United States Secret Service, The Australian Federal Police, The Internal Revenue Service, among others.

Q: Has the CONDOR ever been used for real casework?
A: Yes, this has been used in live document case work.  In the case of

The People of the State of New York vs. Ened Gjelaj and Edmir Gega

in 2006, ChemImage’s hyperspectral imaging system was used by a forensic document examiner from the U.S. Secret Service to evaluate stains on U.S. currency.  Results were presented in court and are a matter of public record.
CONDOR - Hyperspectral Imaging Hardware
Q: Is the CONDOR a transportable unit?
A: No. The CONDOR is a laboratory-based instrument only.

Q: Is there a warranty or guarantee on my purchase?
A: All parts and labor are guaranteed for one year from the date of purchase. After one year, maintenance agreements can be purchased to cover the instrument.

Q: How do I know which CONDOR configuration is best for me?
A: The specific sample type(s) that you are interested in, will determine the configuration that is best for you.
