Randomized Spectral Sampling for Efficient Simulation of Laser Propagation through Optical Turbulence
Daniel A. Paulson, Chensheng Wu, Christopher C. Davis
We present a new method for the generation of atmospheric turbulence phase screens based on the frequency shift property of the Fourier transform. This method produces low spatial…
Surface Wave-Based Underwater Radio Communication
Igor I. Smolyaninov, Quirino Balzano, Christopher C. Davis +1
An underwater portable radio antenna operating in the 50 MHz band and efficient for launching surface electromagnetic waves at the seawater/air interface is presented. The antenna…
Object Detection and Geometric Profiling through Dirty Water Media Using Asymmetry Properties of Backscattered Signals
Chensheng Wu, Robert Lee, Christopher C. Davis
The scattering of light observed through the turbid underwater channel is often regarded as the leading challenge when designing underwater electro-optical imaging systems. There h…
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…
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…
