Abstract
An optical system for responding to distortions in incident light in a free space optical communication system includes a machine learning output storing at least an indication of multiple images and corresponding positioning or orientation attributes for one or more optical elements; a sensor configured to generate an image; and a component configured to adjust the one or more optical elements based on the generated image. Various other methods, systems, and apparatuses are also disclosed.
Claims20
An optical system, comprising:
- a machine learning output that stores:
- an indication of multiple stored images;
- and
- at least one of positioning or orientation attribute values for one or more optical elements corresponding to the multiple stored images;
- a receiver aperture configured to receive a portion of an incident beam of light following propagation of the incident beam of light through a distorting medium;
- a sensor configured to generate an image of a footprint of the portion of the incident beam of light received by the receiver aperture;
- and
- a controller configured to adjust the one or more optical elements based on the generated image and a set of attribute values corresponding to at least one of the multiple stored images.
A method, comprising:
- receiving a portion of an incident beam of light by a receiver aperture following propagation of the incident beam of light through a distorting medium;
- generating, by a sensor, an image of a footprint of the portion of the incident beam of light received by the receiver aperture;
- comparing the generated image to multiple stored images in a machine learning output to find at least one closest stored image;
- retrieving at least one of positioning or orientation attribute values for one or more optical elements indicated by the machine learning output;
- and
- adjusting, by a controller, the one or more optical elements based on the generated image and a set of attribute values corresponding to the at least one closest stored image.
A computer-readable storage device storing computer-executable instructions, the computer-executable instructions comprising:
- instructions for receiving a portion of an incident beam of light by a receiver aperture following propagation of the incident beam of light through a distorting medium;
- instructions for generating, by a sensor, an image of a footprint of the portion of the incident beam of light received by the receiver aperture;
- instructions for comparing the generated image to multiple stored images in a machine learning output to find at least one closest stored image;
- instructions for retrieving at least one of positioning or orientation attribute values for one or more optical elements indicated by the machine learning output;
- and
- instructions for adjusting, by a controller, the one or more optical elements based on the generated image and a set of attribute values corresponding to the at least one closest stored image.
