Abstract
A beam such as a laser beam a known polarization state is passed through the container. An electrical field is created in the container to reduce optical interference while preserving the ability to more accurately measure the concentration of one or more gasses in the container. A change in the polarization state of the beam after passage through the container is detected. Based on the detected change in the polarization state of the beam, the presence of the one or more gasses can be determined.
