Application: System for fabricating an optical element (Patent ID: US20240059600A1)
The patent filed by Northrop Grumman Corp describes a system for fabricating an optical element by welding an array of fibers to the element, measuring angle and position errors of each fiber, calculating corrections for these errors, and then correcting the angle and position of each fiber using the calculated corrections. The system utilizes various means such as optical beam propagation, imaging in far-field and near-field planes, interferometers, and applying forces to bend fibers in the correction process.
Additionally, the system includes features such as using a sapphire rod to apply force for bending fibers, a trim beam shaper array, and the fabrication of different types of optical elements like 1D and 2D beam shaper arrays. The optical element can be part of coherent beam combining (CBC), spectral beam combining (SBC), or hybrid CBC and SBC fiber laser amplifier systems. Overall, the system provides a comprehensive approach to fabricating optical elements with precise angle and position corrections for each fiber in the array.
