基于光电二极管探测器的闪电光辐射信号观测
Observation of lightning optical signals with photodiode detector
摘要
Abstract
The lightning optical signals were measured by a silicon photodiode detector(PDD) at Conghua city Guangdong province and Changping district Beijing city in summer, 2008. Totally, 12 observed data were analyzed statistically. The maximum optical peak magnitude is [10. 97(5. 55)+12. 46] mW/cm2, the 10%-90% pulse rise time is 1. 14(0. 44) ± 2. 02 ms, the 50%-50% pulse-width is [1. 44(0. 49)±2. 07] ms and the single lightning optical peak count is 3. 78(3. 00)±2. 30. The radiance peak is one to two orders of magnitude more and the pulse-width is broader, compared with the FORTE's PDD data. These results are reasonable according to the lightning radiance mechanism and physical evolution process.关键词
