Using an incoherent target-return to adaptively focus through atmospheric turbulence
William Nelson, John P. Palastro, Chensheng Wu +1
A laser beam propagating to a remote target through atmospheric turbulence acquires intensity fluctuations. If the target is cooperative and provides a coherent return beam, the ph…
Using Graph Theory and a Plenoptic Sensor to Recognize Phase Distortions of a Laser Beam
Chensheng Wu, Jonathan Ko, Christopher C. Davis
Atmospheric turbulence causes fluctuations in the local refractive index of air that accumulatively disturb a wave's phase and amplitude distribution as it propagates. This impairs…
Interrelations among scientific fields and their relative influence revealed by input-output analysis
Zhesi Shen, Liying Yang, Jiansuo Pei +7
In this paper, we try to answer two questions about any given scientific discipline: First, how important is each subfield and second, how does a specific subfield influence other…
Determining the Phase and Amplitude Distortion of a Wavefront using a Plenoptic Sensor
Chensheng Wu, Jonathan Ko, Christopher C. Davis
We have designed a plenoptic sensor to retrieve phase and amplitude changes resulting from a laser beam's propagation through atmospheric turbulence. Compared with the commonly res…
