    • A rolling bearing arrangement comprising at least two annular rows of bearing rolling bodies, a first inner ring and a second inner ring next to and coaxial with the first inner ring and a snap ring connecting the inner rings to one another. The snap ring has a radially inwardly projecting first engagement element at the first inner ring and a radially outwardly projecting second engagement element at the second inner ring. Radial depressions in the first and second inner rings receive respective engagement elements. The first engagement element engages into the first depression radially in the direction toward the axis of rotation of the rolling bearing arrangement. The second engagement element engages into the second radial depression radially away from the axis of rotation. Free inner spacing inside each inner ring, with one inner spacing nearer to the axis of rotation than the other inner spacing.
    • 一种滚动轴承装置,包括至少两个轴承滚动体的环形排,第一内圈和与第一内圈同轴并且与第一内圈同轴的第二内圈和将内圈彼此连接的卡环。 卡环在第一内圈处具有径向向内突出的第一接合元件和在第二内圈处的径向向外突出的第二接合元件。 第一和第二内圈中的径向凹陷接收相应的接合元件。 第一接合元件沿着滚动轴承装置的旋转轴线的方向径向地接合到第一凹部中。 第二接合元件沿径向远离旋转轴线接合到第二径向凹部中。 每个内圈内部都有自由的内部空间,其中一个内部间距比其他内部空间更接近旋转轴线。

    • Arrangement, system and method for a polarization effect for a interferometric signal received from sample in an optical coherence tomography (“OCT”) system are provided. In particular, an interferometric information associated with the sample and a reference can be received. The interferometric information is then processed thereby reducing a polarization effect created by a detection section of the OCT system on the interferometric signal. Then, an amount of a diattenuation of the sample is determined. The interferometric information can be provided at least partially along at least one optical fiber which is provided in optical communication with and upstream from a polarization separating arrangement. In another exemplary embodiment of the present invention, apparatus and method are provided for transmitting electromagnetic radiation to the sample. For example, at least one first arrangement can be provided which is configured to provide at least one first electromagnetic radiation. A frequency of radiation provided by the first arrangement can vary over time. At least one polarization modulating second arrangement can be provided which is configured to control a polarization state of at least one first electromagnetic radiation so as to produce at least one second electromagnetic radiation. Further, at least one third arrangement can be provided which is configured to receive the second electro-magnetic radiation, and provide at least one third electromagnetic radiation to the sample and at least one fourth electromagnetic radiation to a reference. The third and fourth electromagnetic radiations may be associated with the second electromagnetic radiation.
    • 提供了在光学相干断层扫描(“OCT”)系统中从样本接收的干涉信号的偏振效应的布置,系统和方法。 特别地,可以接收与样本和参考相关联的干涉信息。 然后处理干涉信息,从而减少OCT系统的检测部分对干涉信号产生的偏振效应。 然后,确定样品的变化量。 干涉信息可以至少部分地沿着与偏振分离装置光学通信和上游的至少一个光纤提供。 在本发明的另一示例性实施例中,提供了用于将电磁辐射传送到样品的装置和方法。 例如,可以提供至少一个第一布置,其被配置为提供至少一个第一电磁辐射。 由第一装置提供的辐射频率可随时间变化。 可以提供至少一个偏振调制第二布置,其被配置为控制至少一个第一电磁辐射的偏振状态,以便产生至少一个第二电磁辐射。 此外,可以提供至少一个第三布置,其被配置为接收第二电磁辐射,并且向样本提供至少一个第三电磁辐射和至少一个第四电磁辐射至参考。 第三和第四电磁辐射可以与第二电磁辐射相关联。
