<p>The method involves detecting intensity distribution of light at a receiver side, and providing an intensity profile course of an intensity maximum value to an adjacent intensity maximum value. Different phase signs are assigned to the maximum values when intensity of the light between the maximum values in the profile course falls below a preset threshold value. Same phase signs are assigned to the maximum values when the intensity between the maximum values in the profile course does not fall below the threshold value.</p> |
