【摘要】：針對紅外波段下濕度對偏振光傳輸特性的影響問題,以自然界中較常見的煙煤粒子作為研究對象,采用蒙特卡洛法仿真研究,不同紅外波段下濕度對線偏光和圓偏光傳輸特性的影響情況及其之間差異特性.結(jié)果表明:在短波波段,線偏光與圓偏光的偏振度隨濕度的增加都呈現(xiàn)逐漸上升的趨勢;在中波波段,隨濕度的增加兩種偏振光都呈現(xiàn)下降趨勢;而在長波波段,濕度對偏振狀態(tài)幾乎沒有影響.進(jìn)一步比較可知,在短波波段,圓偏光具有更好的偏振特性,而在中長波情況下,線偏光的偏振特性更加顯著.因此,在應(yīng)用紅外偏振進(jìn)行探測時,本研究對波段的選取、濕度的控制及偏振態(tài)的應(yīng)用具有重要的指導(dǎo)意義.
[Abstract]:Aiming at the influence of humidity on the transmission characteristics of polarized light in infrared band, the bituminous coal particles, which are common in nature, are studied by Monte Carlo method. The influence of humidity on the transmission characteristics of linear and circular polarized light in different infrared bands and the difference between them. The results show that the degree of polarization of linear and circular polarized light increases gradually with the increase of humidity in the short wave band, the decreasing trend of both polarized light with the increase of humidity in the middle wave band, while in the long wave band, the polarization degree of the linear and circular polarized light increases with the increase of humidity. Humidity has little effect on the polarization state. Further comparison shows that circular polarized light has better polarization characteristics in shortwave band and linear polarized light has more obvious polarization characteristics in medium and long wavelengths. Therefore, this study is of great significance for the selection of band, the control of humidity and the application of polarization state in infrared polarization detection.
