摘要
Aspects of the disclosure provide for a method of forming a communication link between two communication devices using a primary search pattern and a secondary search pattern. A misalignment between a first optical system of a first communication device and a second optical system of a second communication device is detected. The first optical system is rotated according to the primary search pattern, and the second optical system according to the secondary search pattern. At the second communication device, a set of frames is captured. Then, it is determined whether a beacon beam transmitted from the first communication device is detected in the one or more of the captured frames. When it is determined that the beacon beam is detected, the communication link is formed between the first communication device and the second communication device.

The second set amount of time for which the primary device is held in the starting beacon position may correspond to the amount of time a secondary device may take to rotate through the secondary search pattern 700. For example, the secondary search pattern 700 has 12 total frame positions, and the secondary device is configured to acquire 20 frames at each frame position at 5000 frames per second. Therefore, the second set amount of time may be the amount of time the secondary device needs to rotate through all 12 frame positions, or 0.048 seconds. In this way, the primary device may be still while the secondary device follows the secondary search pattern 700.
