Abstract: Techniques are disclosed for aligning a first optical scope with a second optical scope to achieve a line-of-sight communication link between the two optical scopes. In an example embodiment, each scope can include an optical transceiver and camera. The optical transceiver in the first optical scope can include a light array that is used to emit a bright pulse of light as a flash. The camera in the second optical scope captures this flash in a camera image. The camera image can then be processed to spatially localize the flash relative to a central region of a photodetector array in the optical transceiver of the second optical scope. A control system can then drive a positioning system for the second optical scope to adjust the second optical scope's positioning so that the second optical scope photodetector array's central region aligns with the spatially localized flash.
