This article outlines the progress of ancient Chinese lenses from the Pre-Qin Period to the Five Dynasties, and discusses mainly two arguments: First, the"yangsui" recorded and narrated in Lun Heng by Wang Chong of Eastern Han Dynasty may be a plano-convex glass lens; secondly, the"four mirrors" recorded and narrated in Tanzi Hua Shu by Tan Qiao of Southern Tang Dynasty may be a plano-convex lens, a biconvex lens, a transparent planeparallel plate and a concave-convex lens respectively, but what kind of tra...

本文概述了中国古代透镜从先秦到五代的发展进程，着重从古代文献和出土文物的研究出发，结合中国古代社会经济发展水平，论证了东汉王充《论衡》中记述的阳燧可能是玻璃平凸透镜；论证了南唐谭峭的《谭子化书》中记述的"四镜"可能是平凸透镜、双凸透镜、平光镜和凹凸透镜。作者认为《谭子化书》"四镜"段可能实际上是对中国古代透镜发展的阶段性总结。

Based on the hypothesis of rectangle and biconvex section shape of the yarn, and different collocation between the inner warp and outer warp, thickness, section shape of the same structure being considered especially, a model for predicting the elastic property of 2.5-D woven composites was developed. To verify the elastic model, 62 samples of 2.5-D woven composites with 6 various structures were selected and the elastic properties were measured.

An optical element such as a rear projection screen for an image display device comprises at least two substantially rigid sheet members each having a first major surface and a second major surface providing a plane of incidence and a plane of emergence, respectively, through which light is transmitted sequentially. A first sheet member comprises a Fresnel lens, and a second sheet member comprises a lenticular lens array on each of the major surfaces thereof.

一种光学元件，例如用于图象显示装置的背投式屏幕（1），包括至少两个基本为刚性各具第一主表面（21；31）和第二主表面（22，32）的板部件（2；3），分别提供顺序穿过光线（10）的入射面和出射面，第一板部件（2）和第二板部件（3）在其各个主表面（31，32）上分别包含一个菲涅耳透镜（24）和一个双凸透镜阵列33，35。

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.

研究中再以搭配物镜的数值孔径与尺条间距的关系，选择ㄧ适当的市售平凸透镜，使聚焦光点的直径与尺条的间距相近，并使用相同於奈米级长行程双雷射聚焦读头装置的光路设计，如此将可藉由直接量测尺条的表面轮廓变化，以获得一组正交弦波讯号，继而利用讯号四分割与细分割处理，计算出尺条之移动方向与移动量，研制出一实用性长行程双雷射聚焦读头光学尺。
