Appl. No.:

15/914015

Inventors:

- ARLINGTON VA, US
Abbie T. Watnik - Washington DC, US

International Classification:

H04J 14/00
H04B 10/60
H04B 10/50

G06N 3/08

Abstract:

An apparatus includes an optical communications receiver receiving a turbulence-distorted, optical signal. The turbulence-distorted, optical signal includes a plurality of fundamental modes encoded via a combinatorial multiplexings dictionary. The received optical signal includes a plurality of two-dimensional images. Each two-dimensional image of the plurality of two-dimensional images respectively represents received fundamental modes of the plurality of fundamental modes. The receiver includes a neural network trained to assign to each two-dimensional image of the plurality of two-dimensional images at least one respective active fundamental mode of the plurality of fundamental modes and a corresponding accuracy probability based on the dictionary.

Abstract:

A method and apparatus for simultaneous spatial light modulator beam steering and system aberration correction. The apparatus includes a spatial light modulator, a wide-field optical system, the wide-field optical system including at least one optical system aberration; and a camera. The wide-field optical system collimates a light beam toward the camera. The camera communicates with the spatial light modulator via a feedback loop that pre-corrects for the at least one optical system aberration.
