| 摘 要： | 利用飞秒互相关二次谐波信号时间选通技术。实现了对埋藏在高度散射介质中物体的透射成像和反射以析成像。互相关选通门有效地选出携带物体信息的弹道光子和蛇行光子，排除了给成像带来背景噪声的温射光子，分别获得了散射介质中物体的二次谐波一维和二维图像。

| Abstract: | A femtosecond time gating of cross correlation second harmonic generation is shown to be a versatile technique to image objects through various highly scattering medium, and optical coherent tomography (OCT) is achieved preliminarily. The ballistic and snake pulse component, that contain the information of the objects are effectively selected, while the diffuse component which contributes bright background noise to the image is eliminated by time gating of femtosecond cross correlation second harmonic generation. The SHG one dimensioanl and two dimensional pictures of objects hidden in highly scattering medium are recorded, respectively. |
