Abstract

The Faraday filter is studied for use in a lidar receiver system. The transmission of the Faraday filter is measured as a function of temperature and magnetic field for both the 455 and 459 nm lines of Cs. The measurements are made over a sufficiently wide frequency range in order to determine maximum transmission, hold-off, and effective bandwidth. Various types of polarizers are tested to determine their effect on the filter's field of view (FOV). A comparison between the theoretical model and experimental results is presented. An overall system trade-off study is presented for several different receiver systems.
