The new procedure allows the user to examine surfaces with the help of a IR laser and thereby to identify different materials and then present these with imaging.
The most significant difference from the classical spectroscopy lies in the scanning speed of large areas as well.
In this, the procedure is not just restricted to forensics, that is the search, capture and evaluation of fingerprints, but can also be attuned by adjusting to other substances and applied in a wide spectrum of industries.
When a forensic specialist enters a crime scene, he does not know where the usable fingerprints are located. All smaller and/or transportable evidence objects are not examined on-site. After photo documentation at the location, these are packed securely, labelled for forensic examination and transported to the laboratory. For visualisation, various processes and hazardous chemicals must be used; some of these alter the clue to such an extent that the associated DNA tests are no longer possible.
SCANOVIS replaces all these processes with a non-contact and completely chemical-free method. Due to a very fast laser scan, fingerprintscan be found in minutes, made visible and then directly saved digitally in order to compare them immediately with databases. This not only significantly reduces costs, but also the health burden of employees.
With mobile handheld unit planned for the future, evidence can be secured directly at the crime scene and no transport is required at all.
A full inspection of cleanliness in critical areas like operating theatres or ICUs, after they have already been cleaned, presents a big challenge for hospitals. The topic described is repeated to the same extent in the examination of ambulances or medical instruments, which came into contact with the patient.
The available methods of examination are based on poorly imitated samples with incubation times of up to 24 hours, before results are available.
For avoiding production errors, it is state of the art today that the product quality is already monitored metrologically during production. However, a measurement method is necessary for execution, which monitors parameters and threshold values at a very high speed.
Be it, incoming goods check, internal audit, samples or 100% final check of the finished goods, quality assurance is a very important topic today for many companies, for one, to meet one's own, self-appointed standard, and also to follow up on the burden of proof that flawless products have exited the warehouse.
