Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

According to range of the focal distance, dropping UV glue which is crystalline and unexpensive into lens cavity with UV rays, and then forms as soon as solidifies the convex lens. Combining UV curing glue convex lens and variable focus lens, the focal distance range achieves the 8.3~24.5 mm low focal distance effect.

於此之后根据变焦效果的需要，利用UV胶透光性佳、成本低，将UV胶滴定於透镜腔体中，形成一凸透镜，藉由变焦透镜与UV胶透镜结合，焦距变化达到8.3~24.5mm范围的低焦距效果。

When Griffis eagerly anticipates the narrative montage after Hollywood the mainstream, the Chaplin accident in is also emphasizing the single lens' expressive force, although he has also utilized some similar "Modern Time" begins the sheep and worker's two lens such performance montage technique, but more time he in faithful with panoram lens performance movement experience time,"Modern Time" mid summer Luo river the scene which sings in the dining room, the fixed positive panoram angle of view, the similar play's onlooking way, the audience can only see Xia the Luo one-man show, can obtain in merely the dining room from lens' laughter people's response,This is certainly for the more comprehensive clear performance its comedy movement and the scene, but actually unavoidably has "adheres to traitors" suspicion of the stage show.

当格里菲斯在好莱坞引领起叙事蒙太奇的主流之后，卓别林意外的还在强调著单个镜头的表现力，虽然他也运用了一些类似《摩登时代》开头绵羊和工人的两个镜头那样的表现蒙太奇手法，但更多的时候他还是在忠实的用全景镜头表现动作的经验时间，《摩登时代》中夏洛尔在餐厅中唱歌的场面，固定的正面全景视角，类似戏剧的观看方式，观众只能看到夏尔洛的独角戏，仅仅能从镜头之外的笑声中得到餐厅里人们的反应，这当然是为了更全面清楚的表现其喜剧动作和场景，但却难免有&附逆&舞台表演之嫌。

In this paper, we proposed a new method of coupling in terms of the request of the intersatellite optical communication system. Using an aspherical cylindrical lens whose front cylindrical lens is orthonormal to its back cylindrical lens collimates the laser beam, and then is focused by a GRIN lens and couples to the single-mode fiber.
