Imaging sensor interpixel correlation (IC), i.e. pixel-to-pixel interference, lowers the sensor effective resolution and the ability to handle high contrast. This increases color distortion in color filter array sensors. IC is generally overlooked, and challenging to mitigate. Recent findings regarding scientific grade (CCD or hybrid CMOS) sensors, describe non-linearities causing pixel charge accumulation dependent IC. GonioLabs' review article motivates the need for a generalization of the point spread function (PSF) into an irradiance-exposure dependent (IED) PSF, also considering super-saturation. The IED PSF is challenging to characterize and apply, partly due to its non-linearity. However, doing so can improve the MTF irrespective of image sensor technology, and for conventional as well as HDRI imaging.

Posted 2018-12-05 by Mikael LindstrandMikael Lindstrand, gonioLabs, PhD defense
The doctoral thesis “Optical Document Security: Measurement, Characterization and Visualization: in the Light of Visual Evaluation” introduces a system able to measure, characterize and visualize the significant aspects influencing a human based inspection of optically variable device (OVD) features. Such OVDs are critically important for the optical document security industry and high value products such as travel documents (passports) and bank notes. The contribution includes the development of a multidimensional and high-dynamic range (HDR) color measurement system of spatial and angular resolution.

Lindstrand M., Forensic DOVID reader, bridging 1st, 2nd and 3rd line inspection GonioLabs’ DOVID Reader (GDR) provides a spatially resolved trichromatic goniophotometric characterization. The present work discusses how the GDR quantifies optical features and differences between them (defects), as appreciated by perceptual evaluation. GDR Advantages are a) evaluating different DOVID suppliers, b) gaining more detailed understanding of deterioration due to circulation, c) forensic evaluation of different groups of counterfeits potentially originating from the same production equipment.

Lindstrand, M., A Novel Security Hologram General Purpose Optical Scanner
The gonioLabs' DOVID Reader (GDR) is based on a spatially, angularly and chromatically resolved high dynamic range of reflectance measurement principle. The GDR is able to in detail and quantitatively capture the perceptually most important characteristics of DOVIDs. The close link between the principal components of information gained by the GDR and the ditto gained by visual perception motivates the GDR to be of unique relevance for the mutually significant first, second and third line inspection modes.
The ability to perceptually relevant characterization of DOVIDs opens the door to technology-neutral product standards, facilitates unambiguous forensic communication, and greatly enhances detailed visual inspection. In short: improved security.

Every hologram has a unique set of characteristics intrinsic to its interference pattern. GonioLabs has developed instrumentation to measure and record these characteristics, creating a profile of each hologram, which could prove valuable as an evidential or scientific record of the hologram. The company is now offering this service to hologram producers and examiners.
