| Abstract: | Light isolators in common transmitter/receiver antenna coherent laser radars is discussed in this paper. The characteristics of quarter waveplate and Fresnel rhomb are analysed, and the quarter retarders of Ge crystal are designed and produced. The rhomb has been used in the CO2 laser heterodyne detection system, and the transfer efficiency is more than 93 %. |
