Abstract: Apparatus and associated methods relate to a light curtain protection system having a passive optical module arranged to receive, from an active optical module, a light signal such that a reflector reflects, through a polarization control module, the light signal to be received by a receiver in the active optical module. In an illustrative example, the polarization control module includes a half-wave plate aligned with the reflector to impart a first predetermined polarization to the reflected light signal such that the reflected light signal corresponds to a second predetermined polarization when received by the receiver. The polarization control module includes optical elements, such as, for example, a linear polarizer, to receive the reflected light such that the optical elements polarizes the received reflected light signal to correspond to a predetermined polarization. In some examples, the light curtain protection system may advantageously require operating power only for the active optical module.
