Abstract
A local communications apparatus is aligned with a remote apparatus, each apparatus comprising radio frequency (RF) and free space optical (FSO) transceivers with substantially parallel boresight. Coarse alignment is performed using the RF transceiver and fine alignment is performed using the FSO transceiver. A patterned search is performed to locate the RF signal from the remote apparatus and known features of the intensity profile are utilized to locate the global maximum, thus coarsely aligning the pair of apparatuses. A second patterned search is performed to locate the FSO signal from the remote apparatus and an iterative step-search is used to align the FSO signal centroid with the FSO transceiver, thus finely aligning the pair of apparatuses.
