<p>In a beam with orthogonal polarisations, in order to compensate for the possible delay of one polarisation component in relation to another, the two components are separated (6) and the optical path of one of said components (5A) is lengthened using an acousto-optical deflector (8), the deviation of which is controlled according to the delay measured. The path of the other component (5B) is fixed (12-13-14). Subsequently, these two re-phased components are recombined (6).</p> |
