    摘要: An apparatus for analyzing a fluid of volume V includes a filter having a filter surface or area A, the filter being capable of allowing the fluid to flow through the filter surface. The fluid's volumetric flow density, averaged over the filter surface, is jmean. The apparatus further includes a scanner for scanning the filter surface with a scan rate B. The area A is optimized based on the volume V, the scan rate B and the volumetric flow density jmean to minimize the sum of filtering time and scanning time. Instead of one filter, at least two filters may be used each having a different area A. The apparatus also includes a mechanism for selecting one of the filters and placing the selected filter in an operating position, where the scanner scans the filter surface face of the selected filter.

    摘要: A method and an apparatus for generating a polarized light beam to be projected onto an object plane are provided. A converging or diverging light beam (18) is generated. The converging or diverging light beam is projected through a member (22, 52) comprising an uniaxial birefringent material, the uniaxial birefringent material having a symmetry axis essentially parallel to the optical axis (12) of the light beam, and the member being placed at a distance from the object plane. Thereby, it is possible to create, for example a radially polarized beam that can be used for various optical purposes, e.g. for optical data reading/writing or for microscopy.

    摘要: A method for radial tracking in an optical disc drive (1) is described. A DTD tracking error signal (S3) is derived from the wobble-induced signal components (WA, WB, WC, WD) of the optical detector signal (SR). This tracking error signal is relatively insensitive to beamlanding errors, and to differences in the signal amplitudes K of the output signal of individual detector segments. Further, the need for a 3-spot grating is eliminated.A distinction is made between on the one hand a situation where the track being followed is empty and on the other hand a situation where the track being followed is written. In case the track being followed is empty, a DTD tracking error signal is derived from the wobble-induced signal components of the optical detector signal, whereas, in case the track being followed is written, a DTD tracking error signal is derived from the data-induced signal components of the optical detector signal.

    摘要翻译: 描述了一种用于光盘驱动器(1)中的径向跟踪的​​方法。 从光检测器信号(SR)的摆动感应信号分量(WA,WB,WC,WD)导出DTD跟踪误差信号(S3)。 该跟踪误差信号对波束归一化误差以及各检测器段的输出信号的信号幅度K的差异相对不敏感。 此外,消除了对三点光栅的需要。 区分一方面是跟踪的轨道是空的情况,另一方面是写入跟踪轨迹的情况。 在跟踪的轨道为空的情况下,从光学检测器信号的摆动感应信号分量导出DTD跟踪误差信号,而在写入跟踪轨迹的情况下,从数据中导出DTD跟踪误差信号 诱导的信号分量的光学检测器信号。
