Abstract: A reality capture device for generating a digital three-dimensional representation of an environment enables an object within an infrastructure to be surveyed or detected. The reality capture device is compact and easy to use, allowing for fast and reliable capture. The reality capture device can be carried and moved by a mobile carrier, particularly a person, robot or vehicle, and can be moved during a measuring process for generating a digital representation of an environment. The mobile reality capture device includes a localization unit for providing a simultaneous localization and mapping functionality, a laser scanner, and a camera unit. The mobile reality capture device is configured to be carried by a user through the room. The room is surveyed during the movement of the mobile reality capture device. The data from the laser scanner and the camera unit are referenced to each other by means of the localization unit.

Abstract: A method for determining a size or shape related parameter of an effective observation volume for an observation technique for particles undergoing at least partially stochastic motion in a dispersion is based on a time-series of observations. The method involves determining one or more time-dependent characteristics of the dispersion or its particles based on the time-series of observations, determining at least one stochastic motion-related parameter representative for the at least partially stochastic motion of at least one particle in the dispersion, and determining a size or shape related parameter of the effective observation volume by modeling of the at least partially stochastic motion of the particle movement in the dispersion, the modeling taking into account the at least one stochastic motion-related parameter and the determined one or more characteristics.

Abstract: An optical device is described for irradiating at least one object in a medium. The optical device may be a microfluidics device, and comprises at least one integrated planar waveguide that enables providing sheet irradiation of objects in the medium. A characterization system including such an optical device and a corresponding method of characterizing an object or a fluid are described.
