3D imaging may be used to determine the sequence in which the lines or marks were added to a document. |

NEW TECHNOLOGY 3D Imaging adds further depth to VSC8000 document analysis |
|
A new 3-Dimensional imaging feature for the VSC8000 enables document examiners to derive a 3D model of a documents surface topography in order to better analyse security features, pen-tip strokes and other impressions in paper. Making use of the camera and illumination options already present within the VSC8000, the new 3D imaging mode will be of interest to all professional document examiners but will have particular relevance to those involved in the inspection of signatures and handwriting, particularly in cases of proof of provenance and ownership dispute.

A New Fingerprint Workflow: A short video, in which a prototype Crime-lite MLD is used to quickly detect fingermarks on evidence
|
|
NEW TECHNOLOGY Detect and photograph more latent fingermarks without the need for chemical dyes, stains, or powders. |
|
For many laboratories, the application of a post-treatment such as Ardrox, Basic Yellow 40, or Rhodamine 6G, is a time consuming daily task that involves the use of potentially harmful chemicals and requires the appropriate safety equipment to be used. By examining CA-fumed evidence using an R-UV/IR imaging system, it is possible to detect and examine latent fingerprints with no further treatment being required. This eradicates the need to spend time preparing chemical treatments, avoids the need to handle dangerous chemicals, and frees up laboratory staff to perform other duties.
