Ka honoa te ngaohiko ki te karaihe hiko, te taupae whakaata me etahi atu ahuatanga o te huringa o te karaihe, ka huri i te ahua polarization o te ngaru marama, kia huri te marama polarized porohita hei marama elliptically polarized, katahi ka riro te marama polarized raina. na roto i te polarizer, ka whakarereketia te kaha o te marama.I tenei wa, kei roto i te ngaru marama nga korero oro, ka horahia ki te waahi waatea.Ka whakamahia te kaitirotiro whakaahua ki te tango i te tohu tohu whakahurihuri i te waahi whiwhi, katahi ka mahia te huringa ara iahiko ki te huri i te tohu whatu ki te tohu hiko.Ko te tohu tangi ka whakahokia mai e te demodulator, ka mutu ka oti te tuku whatu o te tohu tangi.Ko te ngaohiko tono ko te tohu oro tuku, ka taea te whakaputa mai i te kaiwhakamahara reo irirangi, i te puku riipene ranei, a, he tohu ngaohiko e rereke ana i te waa.
