What is it about?
This paper describes how to use a plenoptic sensor to image and reconstruct a beam with vortex phase structure--which is typically known a branch point problem in wavefront sensing tasks. The plenoptic sensor has really made it easy and straightforward to recognize a branch point phase structure.

Why is it important?
This paper adds merit to the plenoptic sensor in solving complicated wavefront sensing tasks.
Perspectives
Chensheng Wu is currently working as a postdoctoral research associate in University of Maryland College Park. Dr. Wu has successfully modified the light field cameras into a wavefront sensor (the plenoptic sensor) that can be used to solve coherent wave detection problems.
