Method and apparatus for alignment of a line-of-sight communications link
摘要
說明書
Each optical scope 2502 relies on a line-of-sight communication link with another optical scope 2502 for sending/receiving light beams that carry data. The optical scopes 2502 can be mounted on a support 2506. Examples of suitable supports 2506 will vary based on where the optical scope 2502 is positioned; in some instances structures such as poles, towers, platforms, or roofs may be used as supports 2506. For example, in many urban settings, the poles that are used to elevate street lights may be desirable for placement of optical scopes 2502 as it is expected that the areas near or above streets may be largely occlusion-free for line-of-sight communication links. At the time of set up, each optical scope 2502 can be roughly aligned with each other based on rough location and directional positioning (e.g., via a simple GPS location and pointing which may rely on a proper orientation of the device to a known location such as the north star or other GPS coordinates of a landmark or such). This allows the optical scopes 2502 to be visible to each other, such as via their respective camera's fields of view, to permit subsequent fine-tuned alignment.
