1. Why use white light interferometry? WLI 3D microscope provides: non-contact fast accurate repeatable area topography, including shaping, waviness and roughness 2. Interference objectives 2.1 Michelson (1.5x ~ 5x) low magnification large field of view 2.2 Mirau (10x ~ 100x) medium to high magnification medium to small field of view 2.3 Linnik (any magnification) 3. […]
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 […]

今天分享两个工具,用处见标题。 1. engauge-digitizer 项目地址:https://github.com/markummitchell/engauge-digitizer 优势:图像化界面,manual很清晰(超级简化版Origin?)。 前几天向Thorlabs要了780HP的色散数据,技术人员给了我一张Matlab绘制的图,没给数据,于是我需要自己从图片里提取数据点。 软件里的教程很清楚,也简单易用,这里就不多讲了。 最后提取的数据点可以保存到csv文件。 2. latex2png 项目地址:http://latex2png.com/ 优势:简单,会mathtype就行 今天用Illustrator做矢量图,需要在图里加公式字母,我也不想搞一堆代码,编辑ai文件,就StackExchange上找了这个简单好用的工具。具体用法如下: 1) Draw yourgraphs/images in Illustrator. 2) Use http://latex2png.com/. Type your latexequation in there, then preview at 800 dpi. 3) Save theimage, then load into Illustrator. 4) When inIllustrator, select your imported equation image and choose Object –> ImageTrace –> Make and Expand.

之所以要记录下来,就是要让自己以后不要再犯重复的错误,看看自己搞坏了多少实验设备,烧了导师多少科研经费。只希望以后,在这里的内容能越少越好。 (1) 时间:2021-02-25 器件名:15mm, Uncoated, N-SF11 Micro Right Angle Prism, 价格:S$213.90/piece 损坏原因:我要把粘在基座上的prism给清洗下来,所以就把它俩一起放在了小烧杯里,再往里面加了丙酮(Acetone)。大概过了一天,胶水都溶解在了丙酮里,我要把棱镜取出来。(错误操作来了)于是我就用金属镊子去夹棱镜的上下底面,想把它取出来。一个没夹稳,prism就掉到了小烧杯的杯沿,然后再落到了光学平台上。经过这两次碰撞,我的心都碎了。果真,prism的corner破了,更惨的是,它的Hypotenuse surface也出了一个洞。惨兮兮的安慰自己,还好它破的洞是在下方,不是正中间,不然真的完全不能用了(虽然这种情况下,已经极大影响使用了)。 反省一下:其实那时候,我该怎么做才保险呢?我应该先把烧杯倾斜,慢慢把丙酮倒了;然后再把烧杯斜放在多层纸上,用镊子把烧杯里的prism给慢慢挪出来。

1.在Optical Coherence Tomography – Technology and Applications的第36页中,提到: The interference of the two beams will have a spectral modulation as a function of frequency which can be measured using a spectrometer. The periodicity of this modulation will be inversely related to the echo time delay. Therefore, different echo delays will produce different frequency modulations. The echo […]
1.什么是protected silver?什么是enhanced silver? 它们之间有什么不同? 在可见、靠近红外和中红外区域的任何受保护金属涂层中,Protected silver具有最高的反射率,对波长、入射角和极化不敏感。 Enhanced silver主要用来优化某一波长的反射率,对波长、入射角和极化较敏感。
1.怎么调节光源的水平呢? 这里提供了两种方法,一种是光源高度可调的情况下,使用调节架直接调节,还用到了尺子。第二种是光源固定的情况下,利用了两个反射镜和两个可变大小的孔阑。 2.啥是Fiber Optic Pigtail? 它和Fiber Patch Cord有啥区别? Fiber Optic Pigtail可以叫光纤尾纤,Fiber Patch Cord可以叫做光纤跳线,具体的解释见这里。
