摘要
根据超短脉冲激光透过高散射介质成像的电子学全息原理，建立了一套完整的适用于透过高散射介质成像的电子学全息系统．采用该系统，透过厚度为１２ｍｍ、体积百分比为５％的鲜奶和水的混合散射液体，对直径为０．６５ｍｍ的金属丝实现了成像．分析了该技术对脉冲宽度的要求，并对该技术进行了讨论．
According to the principle of electronic holography using ultrashort laser pulse for imaging through highly scattering media, an electronic holography system is established which is suitable for imaging through highly scattering media. This system consists of CCD camera, imaging processor and program of the system for numerical reconstructing and image process. Using this system, an image of metal wire with diameter of 0.65 mm has been obtained, through a 12 mm thick scattering liquid mixture of fresh milk and water. The volume ratio of fresh milk and water is 5%. The demand of this technique on pulse width is analyzed.
