| 中文摘要: |
| 根据闪电探测的需要,利用Anderson局域的概念,以SiO2和Ta2O5为介质材料,设计出了带通位置为闪电特征峰的超窄带通滤光片。统计结果显示,该滤光片的峰位、半峰宽和透过率受每层膜厚随机涨落的影响较小。通过ZZSX-800型真空镀膜机对所设计的膜系进行实际镀制,获得了性能优良的超窄带通滤光片。 |
| 英文摘要: |
| Ultra-narrow band pass filter has been designed to meet the demand of lightning detection, with SiO_2 and Ta_2O_5 as dielectric materials by using the concept of Anderson localization. The wavelength of the pass band has been located at the position same as the strongest peak of lightning. The theoretical statistical results show that the position,(full width at half maximum)FWHM and transmittance of the pass band are insensitive for random deviation of the thickness of each layer.The filter has been fabricated in good property by using ZZSX-800 Vacuum Coating machine. |
