Abstract
A detection device for detecting polarization fluctuation of signal light having propagated through an optical transmission line includes: a differential phase information acquisition unit which acquires information indicating a differential phase of input light as an evaluation target at each of one or more time points; and a determination unit which determines whether the differential phase at at least some of the one or more time points satisfies a predetermined condition.
