AI Technical Summary

Problems solved by technology

In existing microwave photonics systems, optical fibers are usually used for point-to-point signal transmission, but for two platforms with relative motion, long-distance wireless laser transmission of microwave optical signals cannot be carried out by using optical fibers, which makes the application of microwave photonics technology restricted. limit

The main difficulty in long-distance wireless laser transmission of microwave optical signals is to achieve precise beam alignment between two high-speed operating platforms and to control the spatial optical transmission loss within a certain range.
