    • An optical fiber sensing system carries out accurate measurements while avoiding measurement noise factors. For example, effects of the emission power of a light source, fiber insertion loss, fluctuations in the sensitivity of a photo detector, fluctuations in the amplitude of an amplifier, the loss of optical energy due to bending of an optical fiber, the loss of optical energy due to connecting two or more optical fibers, and gain fluctuations of electric circuitry provided on a platform do not affect measurements. A reflective sensor is connected to an end of an optical fiber connected to a light source. The light source outputs physical measurement light and reflected light coming from the reflective sensor is separated into two beams of light. Information on the physical quantity of a measurement target object is detected on the basis of an intensity ratio of the two beams.
    • 光纤传感系统执行准确的测量,同时避免测量噪声因素。 例如,光源的发射功率的影响,光纤插入损耗,光电检测器的灵敏度的波动,放大器的振幅的波动,光纤弯曲导致的光能的损失, 由于连接两根或多根光纤而导致的光能以及平台上提供的电路的增益波动不影响测量。 反射传感器连接到连接到光源的光纤的端部。 光源输出物理测量光,并将来自反射传感器的反射光分成两束光。 基于两个光束的强度比来检测关于测量对象物体的物理量的信息。

    • Provided is an optical fiber sensing system that can carry out measurement accurately without being affected by measurement noise factors other than the physical-quantity attribute of a measurement target object, for example, the effects of the emission power of a light source, fiber insertion loss, fluctuations in the sensitivity of a photo detector, fluctuations in the amplitude of an amplifier or other fluctuations, the loss of optical energy due to the bending of an optical fiber (bending loss), the loss of optical energy due to the connecting of two or more optical fibers by means of connectors (connector loss), the gain fluctuations of electric circuitry provided on a platform, and so forth. A reflective sensor is connected to an end of an optical fiber connected to a light source. The light source outputs physical measurement light. Reflected light coming from the reflective sensor is separated into two beams of light. Information on the physical quantity of a measurement target object is detected on the basis of an intensity ratio of the two beams.

    • A printed material (5) has a transparent base member (51), a first image layer (52) formed on the base member, an intermediate layer (53) formed on the first image layer, and a second image layer (54) formed on the intermediate layer. The intermediate layer has a lower white background layer (531) positioned above the first image layer, a light blocking layer (532) positioned above the lower white background layer, and an upper white background layer (533) positioned above the light blocking layer. In the printed material, a thickness of the light blocking layer is uneven in conformity with undulation of the first image layer, and therefore a surface of the intermediate layer which is in contact with the second image layer is flat. With this structure, it is possible to prevent or suppress the undulation of the first image layer from appearing in the second image layer.
    • 印刷材料(5)具有透明基材(51),形成在基材上的第一图像层(52),形成在第一图像层上的中间层(53)和形成的第二图像层(54) 在中间层。 中间层具有位于第一图像层上方的较低白色背景层(531),位于下部白色背景层上方的遮光层(532)和位于遮光层上方的上部白色背景层(533)。 在印刷材料中,遮光层的厚度根据第一图像层的起伏而不均匀,因此与第二图像层接触的中间层的表面是平坦的。 利用这种结构,可以防止或抑制第一图像层的起伏在第二图像层中出现。
