"We used ultrasound waves to sculpt a virtual optical relay lens within a given target medium, which, for example, can be biological tissue," Maysam Chamanzar, an assistant professor at Carnegie Mellon University in Pittsburgh, Pennsylvania, said.
Chia noted: "Its Magic Leap One smart glasses are futuristic in design with a user-friendly camera, sensors, speakers, memory, and a powerful optical relay. ROBO Global Index member NVIDIA Corporation (NASDAQ:NVDA) provides the glasses' CPU and GPU processing power."
When connecting multiple terminals in an optical network, it is necessary to avoid collisions/contention (figure 1) by having the ability to convert between wavelengths because optical signals of the same wavelength cannot be transmitted in the same optical fiber between the optical relay nodes.
Furthermore, with proper precautions, an optical relay may also be applied to air magnetic breakers.
