【摘要】：基于亥姆霍茲-基爾霍夫衍射積分定理,從理論上推導(dǎo)出消色散均光薄膜微結(jié)構(gòu)參量、入射光參數(shù)和透射光參數(shù)之間的關(guān)系。基于此,分析了微結(jié)構(gòu)參量對透射光振幅分布和散射角度的影響。光束通過消色散均光薄膜時,散射光斑具有光強(qiáng)分布均勻、消色散、散射角度可控和散射光型可控等優(yōu)點(diǎn)。實(shí)驗(yàn)制作出結(jié)構(gòu)最大深度為5μm,散射角為8°×7.5°的薄膜樣品,散射角的理論計(jì)算值與實(shí)際測量值誤差在±0.5°以內(nèi)。此薄膜器件適用于照明體系、液晶顯示器背光顯示、投影系統(tǒng)等。
[Abstract]:Based on the Helmhold-Kirchhoff diffraction integral theorem, the relationship among the parameters of microstructure, incident light and transmission light of the ACS thin film is derived theoretically. Based on this, the influence of microstructural parameters on the amplitude distribution and scattering angle of transmitted light is analyzed. When a beam passes through a dispersive homogeneous film, the scattered spot has the advantages of uniform distribution of light intensity, elimination of dispersion, controllable scattering angle and controllable type of scattering light. A thin film sample with a maximum depth of 5 渭 m and a scattering angle of 8 擄脳 7.5 擄has been fabricated. The error between the theoretical calculation value and the actual measurement value is within 鹵0.5 擄. This thin-film device is suitable for lighting system, LCD backlight display, projection system and so on.
