This invention is a closed-loop fusing process for high precision assembly and fusing methods of segmented optics. The segments are mounted on an active alignment/co-phasing device. As the segments are being fused, the monitor ensures that the segments are fused within the specified amount. If there is any variation, there is a feedback system to the alignment device to make proper real time correction. Background: Large precision optics is currently being used in military defense, industrial fields, and astronomy. Due to the increased demand in this area, large optical sizes are expected to be used. Creating large size optics traditionally requires fabrication of fusing multiple segments of optics to create the finished products. Even though there are current methods to achieve this, it is very time consuming and requires significant amount of monitoring to ensure that each segment that is fused together is aligned in a correct manner and within tolerance. If any of the segments is not fused correctly, it may impact the optical performance of the overall system. Therefore, there is a need for a solution that will ensure that the segments fused together are aligned within the tolerance in an accelerated manner to ensure meeting market demands.
