The HSI Examiner™ 1000
Treated Latent Print on Counterfeit Bill
Digital Image
Hyperspectral Image
ChemImage’s HSI Examiner™ 1000 utilizes liquid crystal-based technology to enhance contrast and improve the visualization of latent fingerprints in comparison to conventional methods. This technology makes possible improved latent fingerprint detection, especially on complex, patterned or otherwise interfering backgrounds.
  • Superior detection and contrast     enhancement capabilities
  • A spectrum associated with each     pixel in the image
  • Rapid data acquisition
  • Nondestructive analysis
  • Powerful image analysis software     package
  • Optimized image contrast     against complex backgrounds
  • Accurate, reliable,     courtroom-friendly results
Images captured through traditional photography are collected at one specific color, with a single barrier filter. With hyperspectral imaging, the use of a liquid crystal-based technology replaces barrier filters with a software-controlled tunable filter. By combining standard digital imaging techniques with common spectroscopic methods, our technology provides increased sensitivity and enhanced fingerprint-to-substrate contrast.

This hyperspectral imaging (HSI) system and software package are designed for a wide array of analyses for large forensic laboratories. Combining digital imaging with spectroscopy, the HSI Examiner 1000 will utilize proven image processing techniques to enhance material contrast and remove substrate interference—making it easier for detailed analysis of a variety of evidence.

  • Compare trace evidence visually and spectrally (tape, fabric, polymers, OC sprays, GSR, etc.)
  • Enhance contrast of latent prints on challenging substrates
  • Visualize blood spatter and transfer stains on dark substrates
  • Visualize and characterize ignitable liquid residue patterns, even on aged evidence samples
  • Visualize gun powder residue patterns
  • Nondestructive sample analysis
  • Large sample compartment ideal for large or bulky items
  • Material specific visualization enabling the analysis of patterns (GSR, blood spatter, etc.)
  • Superior spectral resolution provides high material contrast for better image quality
  • Easy-to-use software features icon driven interface, workspace management, and audit trail
  • Export HSI files as movies for dynamic courtroom presentation
