Abstract: A first optical path pointing apparatus includes a first optical transceiver, a first position sensitive detector, and a first adjuster. The first optical transceiver is configured to transmit a first beacon light to a second optical path pointing apparatus and configured to receive the first beacon light reflected by a second prism in the second optical path pointing apparatus. The first position sensitive detector is configured to determine a first alignment angle of the first optical path pointing apparatus based on first information of a position at which the first beacon light reflected by the second prism reaches the first position sensitive detector and send the first alignment angle to the first adjuster. The first adjuster is configured to adjust the first alignment angle thereby generating an adjusted first alignment angle that satisfies a first pointing precision threshold.
