This paper introduces a mathematical model to evaluate fast and cost-effective 3D image sensors based on single photon detectors. The model will help engineers evaluate design parameters based on operating conditions and system performance. Ranging is based on the time-of-flight principle using TCSPC techniques. Two scenarios are discussed: (i) short-distance range indoors and (ii) medium-dista...

Performance on tests of source memory is typically based on recollection of contextual information associated with an item. However, recent neuroimaging results have suggested that the perirhinal cortex, a region thought to support familiarity-based item recognition, may support source attributions if source information is encoded as a feature of the relevant item (i.e., "unitized"). The author...

Rats with lesions in the perirhinal cortex and their control group learnt to discriminate between mirror-imaged visual landmarks to find a submerged platform in a watermaze. Rats initially learnt this discrimination passively, in that they were repeatedly placed on the platform in one corner of a square watermaze with walls of different appearance, prior to swimming to that same location for th...

The perirhinal cortex is known to play a role in recognition memory and visual perception of objects. A recent single-unit recording study adds to our understanding of perirhinal cortex function, suggesting that it may also play a role in evaluating the significance of objects in a context-dependent manner.

Experiments show that the optical reflectance of a random medium can have a nonmonotonic dependence on wavelength even when its absorption spectrum is flat and its scattering coefficient decreases monotonically with wavelength. Measured at a particular radial distance from the illumination point, the reflectance is almost independent of wavelength over a wide band. The peak wavelength of the re...

We study the intensity spatial correlation function of optical speckle patterns above a disordered dielectric medium in the multiple scattering regime. The intensity distributions are recorded by scanning near-field optical microscopy (SNOM) with sub-wavelength spatial resolution at variable distances from the surface in a range which spans continuously from the near-field (distance ≪ λ) to the...
