    摘要: The invention relates to a microelectronic sensor device for the detection of target components that comprise label particles, for example magnetic particles (1). The sensor device comprises a carrier (11) with a binding surface (12) at which target components can collect and optionally bind to specific capture elements. An input light beam (L1) is transmitted into the carrier and totally internally reflected at the binding surface (12). The amount of light in the output light beam (L2) and optionally also of fluorescence light emitted by target components at the binding surface is then detected by a light detector (31). Evanescent light generated during the total internal reflection is affected (absorbed, scattered) by target components and/or label particles (1) at the binding surface (12) and will therefore be missing in the output light beam (L2). This can be used to determine the amount of target components at the binding surface (12) from the amount of light in the output light beam (L2, L2a, L2b). A magnetic field generator (41) is optionally used to generate a magnetic field (B) at the binding surface (12) by which magnetic label particles (1) can be manipulated, for example 15 attracted or repelled.

    摘要: The present invention refers to a method of operating a self-mixing interference sensor and a corresponding self-mixing interference sensor device. In the method the laser (1) of the device is controlled to periodically emit a laser pulse followed by an emission period of laser radiation having a lower amplitude. The pulse width of the laser pulse is selected such that the pulse after reflection at the object (3) re-enters the laser (1) during the emission period of laser radiation with lower amplitude. The corresponding SMI signal has an increased signal to noise ratio.

    摘要: The present invention relates to an optical system for performing radial tracking on an associated optical record carrier. The optical system contains at least one radiation-emitting device capable of emitting at least three beams: a first beam for reading and/or recording information, and at least a second beam and a third beam for tracking. The optical system is adapted for radial tracking of the first spot from a tracking error signal generated based on the high-frequency component of the central-aperture signal of the second and third beams. The tracking error signal may be generated based on a difference signal of a DC-level of the power of the high-frequency components of the central-aperture signal.

    摘要: The invention relates to an apparatus for measuring a distance. A self-mixing interference (SMI) unit (2) generates an SMI signal, wherein the SMI unit comprises a laser (3) emitting a first laser beam (4) for being directed to an object (5) and wherein the SMI signal depends on an interference of the first laser beam and a second laser beam (6) reflected by the object. A peak width determination unit (8) determines a peak width of the SMI signal, and a distance determination unit (9) determines a distance between the object and the SMI unit depending on the determined peak width of the SMI signal. Since the distance is determined depending on the peak width of the SMI signal, without requiring a laser driving current modulation, advanced electronics for modulating the driving current of the laser are not needed. This reduces the technical efforts needed for determining the distance.

    摘要: An optical storage medium (20) comprises a first data layer (21), for example a Blu-ray (BD) data layer. In addition, the optical storage medium (20) comprises a second data layer (23), for example a DVD data layer. The second data layer (23) is bonded to a substrate (25) using a third layer (27). The third layer (27) comprises an adhesive layer combined with a reactive layer A reactive agent contained in the reactive layer acts to provide a limited lifetime to the data contained in the second layer (23). The second data layer (23) (i.e. having a limited lifetime) contains access data for controlling access to at least some of the data contained on the first data layer (21). In this way, access to a BD layer can be controlled by a separate DVD layer having a limited lifetime.
