利用皮秒激光对高散射介质中的物体成像的研究

Investigation on Imaging Objects Hidden in Highly Scattering Media Using Picosecond laser

本文分析了激光脉冲在高散射介质中的传输特性，研究一种利用皮秒激光二次谐波互相关方法对高散射介质中的物体成像的技术，得到５００μｍ的空间分辨率。

We analysed the characteristics of laser pulses propagating through highly scattering media and studied an imaging technique based on picosecond laser secondharmonicgeneration crosscorrelation ,with which we could sucecssfully image objects hidden in highly scattering media and obtain the spatial resolution of 500 μm. This thchnique may be applied to the medical diagnosis.
