MerrillDepartment of Electrical and Computer Engineering - University of Utah IntroductionOptical Time Domain Reflectometry (OTDR) is a common technique for detecting damage in fiber optic cables. The process involves transmitting a pulse of light down the optical fiber, analyzing the amount of light reflected back to the source, and displaying the reflection patterns on the OTDR screen.During characterization of short fiber optic cables of approximately 1 meter, Fresnel reflections pose a serious challenge to accurate damage detection. The Fresnel tail obliterates any small reflections that are produced by damaged sections of cable, and the damage is overlooked.Simulation MethodThe Finite Difference Time Domain method [1] was implemented in MATLAB to simulate a pulse of light traveling through the patch and test fibers. The following parameters used in the simulation were obtained from an actual OTDR system: Index of refraction (n) of test fiber = 1.4525, Wavelength (λ) of light pulse = 850 nanometers [3] .Plotting the reflection response patterns from all four connection types shows that the Angled Physical Contact connector produced the lowest reflection (see Figure 6). Though much less expensive, Index Matching Fluid only has a lifetime of 2 years. Most optical fiber applications require 10 years life or more [3].Pulse DurationT o determine the effect of the light pulse duration on the saturation level of the OTDR unit, one period ofa raised cosine pulse was transmitted through the fiber at various frequencies. A pulse duration of 1 microsecond proved to be the most favorably responsive for the parameters of the simulation (see Figure 3). In realworld application, however, the duration must actually be smaller due to the relatively slow simulation speed vs. the physical speed of light.OTDR Saturation at Increased Pulse Durations 0.035 1 second 0.03 2 seconds 3 secondsAbnormalities in the fiber, such as bends, cracks, connectors, and other abrupt changes in the refractive index create reflection spikes called Fresnel ( Fre'-nel ) reflections [2]. After a spike is detected, a significant delay occurs when the reflectometer ‘settles down’ from its saturated state. This delay is called a Fresnel tail (Figure 1).Figure 1: OTDR screenshot showing reflection spike from cable connector, and resulting Fresnel tail (area marked by bracket)0.025Electric Field (V/m)0.020.01510.01Figure 5: Reflection patterns using various connectors (reduced Fresnel magnitudes inside yellow box)0.0050 1 1.5 2 2.5 3 3.5 4 Travel Distance from Source (m) 4.5 5SummaryShort fiber optic cables present many challenges that must be overcome in order to accurately detect fiber damage using OTDR. Pulse durations shorter than 1 microsecond, and Angled Physical Contact (APC) fiber connectors are recommended to provide the greatestreduction in Fresnel reflection. By performing OTDRsimulations, an optical systems engineer could understand the behavior of a fiber network and detect potential problems before actual production.Figure 3: Simulated Fresnel Tail skews, then obliterates, the damage reflection at larger durationsConnector TypeThe index of refraction of the patch vs. the test fiber was allowed differ by up to 10%, which created a mismatch at the junction of the two fibers. Four types of connectors were simulated to determine which produced the lowest reflection magnitude.15x 10-3Ideal Reflection Characteristics (No OTDR Saturation)105Figure 2: Simulated ideal response showing fiber damage (small reflection bumps).

学术海报英语作文Academic posters play a crucial role in the dissemination of research findings and ideas within the scientific community. These visual representations serve as powerful tools for effectively communicating complex information to a diverse audience, fostering collaboration, and advancing knowledge in various fields. Crafting an impactful academic poster requires a meticulous approach that balances the effective presentation of research outcomes with the strategic use of design elements.The primary objective of an academic poster is to concisely and clearly convey the essence of a research project or study. This concise format allows researchers to present their work in a visually engaging manner, enabling attendees at conferences or symposia to quickly grasp the key findings and implications. The poster should be structured in a way that guides the viewer through the research process, from the introduction of the problem or hypothesis to the methodology, results, and conclusions.One of the fundamental aspects of effective academic poster designis the strategic use of layout and organization. The poster should be divided into distinct sections, each with a clear and informative heading, to ensure a logical flow of information. This can typically include an introduction, a section on materials and methods, a presentation of results, a discussion of the findings, and a conclusion. By adopting a well-structured layout, the viewer can easily navigate the poster and quickly identify the most salient points.The selection of appropriate visual elements is another crucial consideration in academic poster design. Carefully chosen graphics, such as charts, graphs, and diagrams, can effectively illustrate complex data and findings, making them more accessible to the audience. The use of high-quality images, clear and legible text, and a consistent color scheme can further enhance the overall aesthetic appeal and readability of the poster.In addition to the visual aspects, the textual content of the academic poster must be concise, informative, and engaging. Researchers should strive to strike a balance between providing sufficient detail to convey the significance of their work and maintaining a succinct and focused presentation. The use of clear and concise language, along with the strategic placement of key information, can help the viewer quickly grasp the essence of the research.Another important consideration in academic poster design is theeffective use of white space. Judicious use of white space can help to create a sense of balance and organization, guiding the viewer's eye through the various sections of the poster. This can also help to prevent the poster from appearing cluttered or overwhelming, which can detract from the overall impact of the presentation.The successful dissemination of research findings through academic posters often hinges on the ability to engage the audience and foster meaningful discussions. Researchers should be prepared to clearly and concisely explain the key aspects of their work, addressing any questions or concerns that may arise from the attendees. This interactive component of the academic poster presentation can lead to valuable feedback, collaborative opportunities, and the advancement of scholarly discourse.In the digital age, the importance of adapting academic poster design to online and virtual formats has become increasingly evident. With the growing prevalence of virtual conferences and online poster sessions, researchers must consider the unique challenges and opportunities presented by these digital platforms. Ensuring that the poster is optimized for digital viewing, with clear and legible text and high-quality graphics, can enhance the accessibility and impact of the research presentation.Furthermore, the integration of interactive elements, such asembedded videos or links to supplementary materials, can further enrich the digital poster experience and engage the audience in a more meaningful way. By embracing the evolving landscape of academic communication, researchers can leverage the power of technology to extend the reach and impact of their work.In conclusion, the crafting of an effective academic poster is a multifaceted endeavor that requires a deep understanding of the research, a keen eye for design, and a commitment to clear and engaging communication. By striking a balance between the presentation of research findings and the strategic use of visual and textual elements, researchers can create posters that effectively convey the significance of their work and foster meaningful discussions within the academic community. As the landscape of scholarly communication continues to evolve, the importance of mastering the art of academic poster design will only become more crucial in the pursuit of knowledge and the advancement of scientific progress.。
学术会议的交流主要有两种形式:oral 和poster,就是所谓的口头和张贴两种。
poster,可以译为“海报”或“展板”,扼要展示自己或团队的工作,以供学术交流。
-------------------------------------------------------分割线-------------------------------------------------------------------假装前言话说我有这么门儿课,“学术写作”。
留了个作业,找篇文献,做一个poster。
2-3人小组作业,这个周日deadline。
话说一开始我没有组,正打算单干呢,昨天课前正好撞见我的俄罗斯同学,她说我也没组呀,咱俩吧;她前一天刚报告了一篇文献,说咱就这个吧,我心想也不错,反正自己也没开始。
昨天晚上大概不到10点的时候,这位俄罗斯妹子发来了她的初稿(见图一),邮件里还说“我在这上面花了1个小时40分钟,公平起见吧,你是不是也得差不多花一样的时间捏?”我暗自思忖,行啊,无所谓。
打开初稿一看,出了一身汗,全TM的工作量啊……不过心想她文章看了至少2遍吧,得嘞,开干吧。
图一. poster 初稿从10点大约折腾到凌晨1点找素材,确定模板,然后睡觉去了。
今天早晨8:30起的,起来就断断续续干这件事儿,但累计也得五六个小时了吧。
我在晚上7点时候基本完成了这个poster,妹子给我挑了一些毛病,然后后面说“忽略那些小问题,我非常喜欢这个po ster哈!”(你丫敢不喜欢……)8点半左右基本定型了,明天早起再最后看一眼。
闲言少叙,正题吧。
-------------------------------------------------------分割线-------------------------------------------------------------------正文部分先是一些关于poster的基本要点和原则:•制作软件-PPT!poster的制作软件是PPT,以前一直以为是什么高级软件,但现在发现PPT这货还真是挺强大的。

正文部分
先是一些关于poster的基本要点和原则:
∙P ∙等等。
po

配乐很亮),初次接触的话可以简单学习一下。
?
∙布局:这是接下来一个依旧非常重要的工作,在逐项进行poster制作之前最好做到心中有数。
一个比较可行的方法是找一张白纸大概先画一下,什么地方放什么东西,每个部分占多大地方等等。
布局有好几种方式,但都不能违背阅读的基本顺序:从上至下,由左及右。
这里,十分不建议直接套用模板PPT里的版式,因为实在是不好看;再者了,大家都用一样
的,就“撞衫”了,本来会场人就多,撞衫容易降低poster的吸引程度(不过话分两头说,没准儿俩一样的poster有人觉得新鲜呢)。
∙???那用什么样的布局呢?
∙???俗话说“熟读唐诗三百首,不会作诗也会吟”,说的就是个积累和模仿。
去网上找一些poster的例子,大概看几十个,什么是好的什么是不好的心里就有数了。
比如我这个例子,
的母
R
”,比
好多这方面的软件,我并不太了解,就不瞎推荐了。
??????????????????????????????图四.UnivofRochester官网给出的配色建议
∙字体和字号:字体的话中文建议类似“微软雅黑”的字体,英文建议类似“Helvetica”(A rial就是模仿它!)的字体。
学术一点儿,叫无衬线字体(sansserif),说的是笔划的粗细
大体一样。
与之相对的则是有衬线字体(serif),笔划的粗细不一样,比如宋体、TimesN ewRoman。
∙???字号(通常情况,不能强求):全篇的大标题70-100磅,作者50-60磅,机构30-40磅;正文中,小标题48磅,正文内容28磅,参考文献等小字号文本20磅。
∙文中的正文:强调的部分用加粗(Ctrl+B),不推荐使用下划线(Ctrl+U);可以使用斜。
我倍感
你干了什么;如果是个和你研究领域接近的人,这段描述应该能让他在脑海中浮现出你是怎么做的。
做到充分但不絮叨。
没有必要做过多的解释。
这块儿一般还分为这么几个子版块:被试(participants),刺激(stimuli),条件(conditions),程序(procedure)等,逐一介绍。
这一块的内容可以充分运用PPT内的插入表格或者SmartArt做一个流程图,也就省去了全是文字的苦恼。
∙结果(Results):这里有一个大家都知道的原则图>表>文字(牢记啊!!!)。
故而,能用图表说明的东西,就没必要码字了。
在图表上需要标出来你认为重要的结果,比如标注上显着性指标,比如画个圈、打个箭头什么的。
没有必要把统计量(诸如F值、P值等)贴上去。
结果可能有很多,可以用数字(1、2、3、…)或字母(a、b、c、…)做一个引导。
∙讨论或结论(Discussion/Conclusion):还真没见过这两部分都有的poster。
这里的要点
