Abstract:
A spatial light communication equipment comprising:a first optical antenna for receiving spatial light from a remote spatial light source; a deflector for deflecting the received spatial light, the deflector having a first reflecting plane and a second reflecting plane, the first reflecting plane and the second reflecting plane being disposed on opposite sides of the deflector; a detector for detecting an angular deviation of the received spatial light relative to a specified optical axis; a controller for adjusting the first reflecting plane to correct the angular deviation of the received spatial light deflected by the first reflecting plane; and a second optical antenna optically coupled to the deflector for transmitting spatial light reflecting off the second reflecting plane; wherein the second reflecting plane of the deflector is physically coupled to the first reflecting plane of the deflector and moves responsive to the adjustments made by the controller to the first reflecting plane.
