1.Compact polarization splitter based on silicon grating-assisted couplers
简评:研制紧凑型PBS。
简评:随机扰动模型,建立横向血流速度图。从FFOCT想到的横向速度图的方法。
The data processing includes four steps:
- (1) Utilizing differential operation to remove DC signals;
- (2) square operation (which is equivalent to a full-wave rectifier);
- (3) the short-time average of It to eliminate the term bt2 from the envelope;
- (4) low-pass filtering to separate the envelope from high frequency signals caused by random phases.
简评:lens free是好事?光源频率随时间变化。
4.Effect of spherical aberration on laser beam self-focusing in the atmosphere
简评:不同环境下的球差的影响。
简评:用coded pattern当媒介(medium)进行体扫描,获取三维信息。类似手段还有:
- 条纹投影(souce pattern)
- 结构照明(source pattern varing)
- 散射媒介(coded pattern on the scattering medium)
