1. Imaging pulse wave propagation in human retinal vessels using full-field swept-source optical coherence tomography

简评:恰巧昨天收到本文作者GEREON HÜTTMANN的邮件,还再考虑如何回信。不同于传统FF-OCT,该组专注在扫频光源的FFOCT。

2. Simultaneous multi-channel absolute position alignment by multi-order grating interferometry

简评:作者搭建了多级次光栅干涉系统,决定光栅标记的绝对位置。低次级信号确定测量范围,高级信号确定测量精度。最小精度可达11.48nm。是一个比较使用的绝对位置对齐系统,这对很多机械制造有一些帮助。

3. Binary coded patterns for photon control using necklace problem concept

简评:似乎是解决一个叫「pseudo-disordered patterns」的问题。

4. Three-dimensional temperature field measurement of flame using a single light field camera

简评:用光场相机采集物面的温度(即辐射度)场。很有意思的文章,探测到的信号再根据已有的正交分解算法,拟合出相对黑体的RGB三色的辐射度图。

5. Stress-induced birefringence and fabrication of in-fiber polarization devices by controlled femtosecond laser irradiations

简评:用光线内部的双折射可以通过飞秒激光器辐射控制。正如:

Using a fs laser, parallel stress rods were fabricated inside the cladding of a single-mode fiber.
These stress rods produced asymmetric refractive index distribution to the fiber core and
created birefringence in the fiber. The amount of birefringence can be controlled by the
dimension and relative alignment of the cuboid stress rods.

PS:北京时间元月二十日早晨七点跟UCB的Dr.Tan进行了conference call,感觉不错,这是一个双方看合适与否的交流。谢谢他,非常!
