One such experiment sent data between two satellites that were separated by over 18,000 miles. Space agencies are also exploring optical techniques to improve communications to very distant space probes. Some college campuses and large business complexes are experimenting with optical through-the-air techniques for high-s peed computer networks that can form communications links between multiple buildings. Some military bases, banks and government centers are using point-to-point optical communications to provide high speed computer data links that are difficult to tap into or interfere with. But, don't become overwhelmed, there are many simple and practical applications for you experimenters. Several such applications will be covered in this handbook. Below are some examples of existing and possible future uses for light-beam communications. |
