Last updated:
Abstract:
An optical device is disclosed. The optical device has an optical path and includes a first polarizing filter positioned in the optical path that is configured to receive electromagnetic radiation (EMR) from a scene and to transmit a first subset of EMR comprising EMR in a first waveband that has a first polarization orientation and EMR in a second waveband. A second polarizing filter is positioned in the optical path downstream of the first polarizing filter that is configured to receive the first subset of EMR and to transmit a second subset of EMR comprising EMR in the second waveband that has a second polarization orientation and the EMR in the first waveband that has the first polarization orientation.
