Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...
The homogeneity map method for speckle reduction in diagnostic ultrasound images
(Elsevier B.V., 2015)
This paper proposes a new method to reduce speckle noise in diagnostic ultrasound images by improving the speckle reduction capacity of an edge-sensitive filter. A homogeneity map is generated according to the local ...
