    • A marking device includes a marking mechanism, a marking portion moving mechanism, and a pressure adjusting circuit. The marking mechanism marks a surface to be processed, of an object to be marked, by reciprocating a marking portion. The marking portion moving mechanism moves the marking portion in two-dimensional directions along the surface to be processed. The pressure adjusting circuit keeps a constant pressure which the marking portion applies to the surface to be processed. The marking mechanism includes a cam mechanism for linearly reciprocating the marking portion by following a cam which is rotated by a driving member.
    • 标记装置包括标记机构,标记部分移动机构和压力调节电路。 标记机构通过使标记部分往复运动而标记待加工物体的待标记物体。 标记部移动机构沿着被处理面向二维方向移动标记部。 压力调节电路保持标记部分施加到被处理表面的恒定压力。 标记机构包括用于通过跟随由驱动构件旋转的凸轮使标记部线性往复运动的凸轮机构。

    • An apparatus and method for accurate measurement of characteristics of optical fibers (distribution of polarization mode dispersion and distribution of magnitude of birefringence). Pulse light is inputted to a subject optical fiber, back scattered light of the pulse light from the subject optical fiber is detected by a photodetector to find a Stokes vector, and polarization mode dispersion in a longitudinal direction is measured. The apparatus comprises a light source unit for outputting the pulse light having at least three different angular frequencies, and an arithmetic operation unit for calculating the magnitude of linear polarization components and the magnitude of a circular polarization component of a polarization dispersion vector on the basis of the Stokes vector and thus calculating polarization mode dispersion.
    • 用于精确测量光纤特性的装置和方法(偏振模色散的分布和双折射大小分布)。 脉冲光被输入到目标光纤中,由光电检测器检测来自目标光纤的脉冲光的反向散射光,以找到斯托克斯矢量,并测量纵向上的偏振模色散。 该装置包括用于输出具有至少三个不同角频率的脉冲光的光源单元和用于基于以下方式计算偏振分散向量的线性偏振分量的大小和偏振分散矢量的大小的算术运算单元 斯托克斯矢量,从而计算偏振模色散。
