好快哦，转眼又是一个月了。 Emmmm，还记得四月底的那会儿，老板还和我说了五月的安排，“五月份做完实验，获取所有的数据，六月就可以开始写文章了。” 嗯~ o(￣▽￣)o，信心满满，理想总是美好的，但是，然后就到了现在。整个五月我都在做模拟中，也不是说没有任何进展，但我觉得自己的进度还是太慢了，脑子总是想着要做这个、要做那个，但是手脚总是动不了。 这的确是需要反思的。另一方面，我觉得值得肯定的是：当我做了每周的计划，我可以做到有迹可循，虽然有时候会没法完全按这个做，但至少每天可以有一个小目标。还有一点，就是每天的小总结，可以帮助自己回顾一天的工作内容。 接下来的时间，主要会有三个目标：第一个是完成qualify written exam（必须要过，不然就退学了==）；然后就是开始写文章了，必须写了（我知啊，实验完全没做好，根本不完整，但是，可以开始动笔了）；最后一个，但其实也是很重要的，权衡一下做怎么样的实验、怎么做实验，才能得到最好的效果。 说完了科研，扯些其他的吧。都说一个合格的导师，必须首先得会给学生画饼。嗯，确实，我也非常赞同。我觉得嘛，导师画饼可能有各种各样的目的，一是真心为了学生的未来着想，但也不排除其中包含有自己的利益，另一种就不怎么好了，完全是为了个人，或是项目、或是人力，各种因素都有可能。当然，要是我老板都已经懒得和我说话，觉得我并不重要了，画饼的说法也自然不存在了。 我自己认为，博导和学生之间更多应该是合作的关系，或者说这样才是健康正常的关系。有时候这种关系也许不会显得完全平等，但双方应该是相互需要、不可分割的。导师愿意和学生分享除了学术以外的观点（不只是画饼，也许还有人生观、择业观），这对学生来说完全是非常利好。我觉得可行有用，自然可以采纳；我觉得这太过了，甚至有洗脑的嫌疑，心里就需要留个心眼。过来人的经验必然有其价值，但并不都是可取的。实践在每个人身上的实现方式并不相同（我忘了高中思政课本上的话是咋说的了，大致这个意思，忽然觉得有必要读个毛选？？？）我并不相信导师说的所有话，但我赞同他很大部分的观点。 不得不承认，我导师对我的影响还是挺大的。比如他曾经和我谈的毕业出路问题，虽然他没有明说，（我也知道他肯定不会指定某个人的择业意向），但从他的建议和提议中，我可以深刻地感觉出他自己对我的引导。我之所以喜欢平时找他聊，就是觉得可以从沉重的科研环境里逃离片刻（哈哈哈哈，没想到吧，似乎反着来了）科研聊片刻，其他时间就可以说点其他的，说完既缓解了压力，又有了点新的目标（有时候也会听的有点累hhhhh）。我也忙，他也忙，但老板每次都说，有事随时来找他，感动（我真信了，真的随时来，扑空了好多次，以后还是得提前问）。 哎，咋几句话不离科研，女朋友找到了么？！？你这么努力科研，考虑过爸妈么？！？(/doge)真是的。 生活啊，不知不觉，科研和生活已经同化了，变成了“科研生活”，我觉得以后，就应该把“科研”换成“工作”，这样“工作生活”就很别扭了吧，科研就是工作，工作不是生活，得出结论：科研不是生活，bingo(o゜▽゜)o☆[BINGO!] 那我的生活是不是只有早上起床的两小时和晚上睡前的两小时？？？还加上周末上午的睡觉时光，哈哈哈哈嗝~ 我相信自己还是能找到适合自己的状态的。
The reviewed paper is Rapid-scanning forward-imaging miniature endoscope for real-time optical coherence tomography. One advantage of forward-viewing OCT endoscope over transverse-imaging counterpart is that it eliminates the need for mechanically actuating the entire endoscope assembly or a rotational fiber-optic coupler. Another possible merit is that the lateral-priority image acquisition sequence greatly reduces the depth-scanning speed. […]
This old paper introduced two setups of forward-viewing instruments for optical coherence tomography (OCT). In the beginning, the author mentioned one advantage of forward-viewing devices: permitting data to be collected before the device is introduced into the tissue. I assume it’s because of forward-viewing OCT’s characteristics. Two setups were proposed: a hand-held probe, and a […]
By the end of February 2022: Demonstrate the first workable fluid-shaped probe; Should be able to achieve reflecting and focusing; By the end of March 2022: Polish the result, including optimizing resolution, depth of focus, reflectance, and back-reflection Apply it to animal imaging to demonstrate ex vivo and in vivo imaging; Start writing the manuscript.

It is not the first time that I read the paper "Fabrication of freeform optical components by fluidic shaping", but I have to admit that I did not get a very good understanding of it. This time, at least I can throw some questions to myself and offer a certain way for the next step […]
The paper ‘Fabrication of diffractive optical elements by programmable thermocapillary shaping of thin liquid films‘ proposed a new method to fabricate diffractive optical elements, that is, using the variable temperature distribution to induces surface tension gradients in the polymer-air interface. Gradient surface tension leads to the deformation of the interface, and the two-dimensional temperature distribution […]
问题描述： I would like to simulate that light travels through a single mode fiber and a coreless fiber, and the end of the coreless fiber is a tilted flat surface, so the light will be reflected because of total internal reflection or reflective coating. My problem is that I can not keep the aperture constant […]

If you are interested in this paper Shot-noise limited, supercontinuum-based optical coherence tomography, please find it here. Main contribution Current supercontinuum (SC) -based SD-OCT system cannot be operated in the shot-noise limited area because of its strong pulse-to-pulse relative intensity noise of the supercontinuum source. The authors propose an all-normal dispersion (ANDi) fiber based supercontinuum […]
1 Ultrahigh-resolution, high-speed, Fourier domain optical coherence tomography and methods for dispersion compensation In OCT, dispersion compensation is usually performed by matching the optical materials and path lengths in the two interferometer arms. Dispersion can also be compensated by using numerical techniques. Principle of SD-OCT: The sample is illuminated with broadband light. Backreflected or backscattered […]
