Abstract:
A method for the alignment of optical interconnections between at least one optical data transmission point and at least one corresponding optical data receiving point, comprising:a) providing a data carrying light source for transmission from said transmission point; b) providing an optical sensor for receiving data carrying light at said receiving point, said sensor providing an electrical signal which is related to the energy contained in said data-carrying light; c) providing an electrically-controlled light polarizer consisting of an array of pixels, located between said data transmission and receiving points, such that the beam of said data-carrying light is forced to pass essentially through at least one active area of said polarizer in order to be polarized; d) collimating said beam with a lens, such that the collimated beam passes through a plurality of the pixels; and e) obtaining a focused beam of said data-carrying light, emitted from said light polarizer, on said receiving point, by individually controlling the polarization of each pixel, and deflecting the direction of said collimated beam when emitted from said light polarizer, until a predetermined value of said electrical signal is obtained.
