Abstract: A manufacturing system includes a holding structure and actuators that are coupled to the holding structure. The actuators support the component and apply displacements to select locations of the component to change a current shape of the component toward a target shape of the component. The system includes a metrology system that takes measurements of the current shape of the component. The system includes a controller that utilizes a closed feedback loop to determine a deviation between the current shape and the target shape based on the measurements and to provide commands that iteratively change the displacements in response to changes in the current shape until the current shape is within a tolerance of the target shape.

Abstract: A laser defense system may be used to generate a plasma shield for protecting a structure against a directed-energy source. The laser defense system may include a short pulsed laser which generates plasma in a plasma shield region between the structure and the directed-energy source. Because plasma is opaque to electromagnetic radiation, the laser signal emitted by the directed-energy source is absorbed by the plasma shield rather than striking the structure.

Abstract: A computer vision method and computer vision system can be used to process a time-based series of images. For a subject image of the time-based series, a light intensity value is identified for each pixel of a set of pixels of the subject image. A light intensity threshold is defined for the subject image based on a size of a bounding region for an object detected within a previous image of the time-based series captured before the subject image. A modified image is generated for the subject image by one or both of: reducing the light intensity value of each pixel of a lower intensity subset of pixels of the subject image that is less than the light intensity threshold, and increasing the light intensity value of each pixel of a higher intensity subset of pixels of the subject image that is greater than the light intensity threshold.

Abstract: A method of forming an object from a material includes directing a first beam of light toward a first target location of the material to define a first portion of the object. The method also includes, after directing the first beam of light toward the first target location, determining an optical correction to be applied by an optical system. The optical correction is based on an atmospheric change in an atmospheric distortion region proximate the first target location due, at least in part, to interaction of the first beam of light and the material. The method further includes directing a second beam of light toward a second target location of the material to define a second portion of the object. The second beam of light is directed through at least a portion of the atmospheric distortion region while the optical correction is applied.

Abstract: A method communicates data with a platform. A platform receives modulated coherent optical signals modulated using radio frequency signals encoding sensor data and generates an input current in response to receiving the modulated coherent optical signals at a receiver system in the platform. The platform recovers the radio frequency signals from the input current in a manner that adjusts for changes in the modulated coherent optical signals caused by variations in received optical intensity occurring during propagation of the modulated coherent optical signals. The platform outputs the radio frequency signals encoding the data.
