CMOS imager targets forensic applications
Researchers at HP Laboratories describe a 1:1 magnification 3.5 micron true resolution Dyson Relay lens-based 3 MPixel USB CMOS imaging device and software forensic image analysis system.
In their article “High-Resolution Glyph-Inspection Based Security System,” Steven J. Simske and Guy Adams of HP Laboratories describe the use of a 1:1 magnification 3.5 micron true resolution Dyson Relay lens-based 3 MPixel USB CMOS imaging device (DR CID) and software forensic image analysis system.
The device enables the simultaneous capture of both intentional printing shapes and unintentional printing artifacts caused by the printing process and the interaction of the ink with the substrate on which printing occurs. The custom image analysis system written for the DR CID device allows even a single printed character to simultaneously provide fiducial marking, inspection information, authentication and forensics.
