U.S. Air Force scientist Matthew Squires has invented a positioning device for the stable and repeated coupling of a laser beam and a fiber optic cable. The patented technology is available via license agreement to companies that would make, use, or sell it commercially.
The device contains four prisms (two Risley prism pairs) that can change the laser beam’s angle of incidence and position.
The prisms are precisely manipulated by an electric motor, which is directed by a computerized controller connected to an optical sensor that provides feedback on the beam coupling.
The controller’s software allows the device to effectively mitigate or eliminate hysteresis.
- Precise, repeatable beam alignment
- Businesses can commercialize the technology by licensing U.S. Patent 10,495,829 from the Air Force
- License fees paid to the Air Force are negotiable
