搵到了,21年nikon 報告寫 In December 2020, Nikon partnered with SoftBank Group Corp. to perform the world’s first successful verification test* of a tracking optical wireless communications technology that allows for 360-degree tracking between two transmitters through the use of artificial intelligence, image processing, and precision control technologies. Optical wireless communications are resilient to electromagnetic interference while also being incredibly secure. However, as light travels in a straight line, it has been difficult to apply this communications method to transmissions between moving bodies. The verified technology allows for communications between such bodies and therefore has the potential to contribute to the creation of new markets in fields like communications between vehicles and between vehicles and roads; communications among unmanned transportation vessels, other industrial robots, and drones; and communications underwater, where electromagnetic waves cannot be transmitted. SoftBank and Nikon will continue research and development and verification tests aimed at creating markets in such new fields going forward. Tracking optical wireless communications technology verification test * This test was a world first as of March 18, 2021, according to surveys by SoftBank and Nikon. Specifically, this was the first verification test to confirm an ability to track and maintain uninterrupted communications between two optical wireless transmitters moving in self-determined directions.
The first company to use aspheric technology for eyeglass lenses was Essilor, which introduced the first aspheric lenses for prescription eyewear in the early 1980s. This innovation allowed for thinner and lighter lenses, improving both comfort and aesthetics for wearers. Aspheric lenses provide better optical performance by reducing distortion and improving vision quality, especially in the peripheral areas of the lens compared to traditional spherical lenses.
