摘要 | High precision atmospheric detection spectrometers are widely used, because the sunlight would be polarized while passing the atmosphere and that could reduce detecting precision of the devices. There are many efforts on removing this influence. An allotype double H-V(Horizontal-Vertical) depolarizer is proposed, and it is equipped on hyperfine spectrometer used for atmosphere detecting in UV. Because the birefringence structure of crystals could eliminate the polarization, they are always chosen for depolarizers. Essentially, the birefringence of depolarizer can induce depolarization and double-imaging at the same time. The difference between traditional structure and the allotype is the inequality of the wedge angles of two sub H-Vs. There are different double-imaging distances in the spectrum dimension and the spatial dimension. So the contradiction between high depolarization and high-imaging quality could be resolved. This paper will describe the design and analyzed the result. Depolarization is better than 98.8% and distance of the double-imaging is just 8.7% in the spatial dimension.
