摘要: Method and apparatus for the alignment of optical interconnections between at least one data transmission point (104) corresponding receiving (107). A collimated beam (201) carrying light is polarized through an electrically-controlled polarizer (108), such as a spatial modulator or liquid crystal, which comprises array pixels. focused (202) data-carrying light, emitted from polarizer, obtained on point, by individually controlling polarization each pixel, deflecting direction when until predetermined value electrical signal (current and/or voltage) representing level obtained. The further continuously adaptively aligned determining desired current threshold voltage produced sensor point. comparator circuitry compares actual sensor, to current, feedback loop controls individual pixel according comparison result.
