| 摘 要： | 用波长为630 nm的激光器作为光源,硅二极管直接接收气泡幕的散射光.对不同气泡幕的散射光作不同点的均值,同时用Matlab语言程序计算散射光不同点自相关,充分证明了散射光的随机性.从散射光的统计性质来看,它的均值和相关性与气泡幕参数之间存在一定的规律,使光探测尾流具有可实现性. |

| Abstract: | Lamp-house was laser which wavelength is 630 nm,the light scattered by air bubbles wall was incepted by Si-diode. The scattered light’s mean value of different air bubbles wall was calculated at different point. Scattered light was analyzed with auto-correlation using Matlab procedure contemporary. Thus the random of scattered light was proved. From the scattered light’s statistical character,its mean value and auto-correlation have some orderliness with the parameter of air bubbles wall,which can realize the detection of light to wake. |
| Keywords: | Bubble Wake Scattered light Random signal Correlation |
