  • APPLICATIONS OF OPTICALLY STIMULATED

    INTRODUCTION. The optically stimulated luminescence (OSL) technique is now well established and widely used in various dosimetry applications, but particularly in luminescence dating and personal dosimetry. The technique is based on the optical stimulation of trapped charges created by ionizing radiation, resulting in luminescence whose intensity and total emission are proportional to the dose ...

  • OSL | Embedded

    Writing a device driver requires an in-depth understanding of how the hardware and the software works for a given platform function. Because drivers require low-level access to hardware functions to operate, drivers typically operate in a highly privileged environment and can cause system operational issues if something goes wrong.

  • GChron - Towards an improvement of optically

    Abstract. Statistical analysis has become increasingly important in optically stimulated luminescence (OSL) dating since it has become possible to measure signals at the single-grain scale. The accuracy of large chronological datasets can benefit from the inclusion, in chronological modelling, of stratigraphic constraints and shared systematic errors.
