摘要： A plastic fiber having optical transmission properties which consists of a core layer (1), a sheath layer (2) and a protective layer (3) as fundamental constituent units. The protector layer (3) has a thermal deformation temperature ADHDT BD higher than 120oC, a thickness greater than 10 mum, and has a sectional area of greater than 0.07 times the total sectional area of the core layer (1) and the sheath layer (2). This enables the plastic fiber to exhibit good optical transmission properties even at high temperatures. More preferably, the plastic fiber having the optical transmission properties of the above-mentioned structure is further provided with a plastic covering layer (4) which has a silane crosslinked structure.

摘要： A color image scanner comprising a three primary colors LED array (4) for illuminating a material (2) to be read, a monochromatic image sensor array (3), and a rod lens array (1) which is provided between the material (2) and the image sensor array (3). Three types of distributed refractive index rod lens (11, 12 and 13) constituting the rod lens array (1) have different operation wavelength bands and predetermined wavelengths in accordance with the type and have same lens length Z0 regardless of the type. The focus parameters of the types of the rod lenses are so set as to make the conjugate lengths TC of all the types at the predetermined wavelengths substantially equal to each other. In order to read a color image by using the rod lens array which is advantageous from the viewpoints of size reduction and brightness, the chromatic aberration of the rod lens array can be sufficiently reduced and the high resolution can be realized at a low cost.
摘要翻译：一种彩色图像扫描仪，包括用于照射待读取的材料（3）的三原色LED阵列（4），单色图像传感器阵列（3）和设置在材料（2）之间的材料（2））和图像传感器阵列（3）。构成棒状透镜阵列（1）的三种分布式折射率棒状透镜（11,12,13）根据类型具有不同的工作波长带和预定波长，并且具有相同的透镜长度Z0，而与类型无关。棒状透镜的类型的聚焦参数被设定为使预定波长的所有类型的共轭长度TC基本相等。为了通过使用从尺寸减小和亮度的观点来看是有利的棒状透镜阵列来读取彩色图像，可以充分降低棒状透镜阵列的色差，并且可以以低成本实现高分辨率。

摘要： A distributed refractive index optical fiber having a multilayer structure of concentric layers made of (co)polymers selected from the group consisting of homopolymers HP1, HP2, ..., and HPn manufactured from two or more kinds of monomers M1, M2, ..., and Mn and having refractive indexes gradually lowering in this order, and one or more kinds of binary copolymer CP of these monomers. Mixed layers of mixtures of the (co)polymers of the adjacent layers are formed between the adjacent layers. The central portion of the optical fiber has the highest refractive index, and the refractive indexes of the optical fiber decreasing gradually toward the outer circumferential portion thereof. This optical fiber can be manufactured continuously by supplying (co)polymers to a concentric multilayer nozzle, and drawing the (co)polymer therefrom. The polymers mutually diffused among the layers.
