3D measurement of tool traces, projectiles and tissue samples

InfiniteFocus in forensics

The 3D measurement of tool traces, fractures or projectiles can lead to the used weapon and consequently to solve a crime. In addition InfiniteFocus is used in criminology for measuring human tissue samples and bones. Measurements with true color information reinforce findings of an investigation.

Identify weapons by measuring tool traces

  • 3D measurement of tool traces such as scratches or abrasion allows the identification of the respective weapon
  • measurement of a projectile’s firing pins across large measurement areas and in high resolution to identify the used weapon
  • even the measurement of reflective and/or very smooth weapon surfaces delivers results of high vertical solution of up to 10nm are
  • human tissue samples and bones are measured in 3D
  • by visualizing measurement results with true color information findings of an investigation are reinforced

Verify the authenticity of paintings

  • 3D surface measurement for distinguishing original artwork and forgery
  • automatic comparison between the surface geometry of the exhibit in question and the original’s topography
  • immediate identification and demonstration of a forgery via colored visualization of geometrical deviations
  • non-destructive measurement of sensitive surfaces and across large areas

More applications of InfiniteFocus in forensics

  • forensic medicine
  • explosives
  • wood, metallic and synthetic materials
  • document analysis

3d micro-coordinate measurement technique for roughness and form measurement

Alicona offers optical 3d surface measurement systems for quality assurance in research and production. Core competence is the measurement of roughness and form also across large measurement areas and volumes. The cutting edge measurement and the measurement of small radii and angles are typical applications. Focus-Variation, the core technique of the InfiniteFocus line, combines the traditional surface metrology and the micro coordinate measurement technology. This technology achieves traceable and repeatable results in highest resolution even in production.
