Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental wave's aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
首次从三维三波相互作用方程组推导得到了位相畸变光束倍频的小信号解;通过建立三维数值模型,编写相应仿真程序,首次得到了位相畸变光束倍频过程的大量计算结果,深入细致地研究了位相畸变光束经非线性光学频率变换后谐波的转换效率、光强分布、位相分布以及影响它们的各种因素;得出谐波的远场发散角和光斑二阶矩的变化规律会因为基波像差的不同而不同,但谐波的远场发散角明显地比相应基波的小的结论;得到了在走离效应和衍射效应等影响许多因素可以忽略的情况下,位相畸变传递到二次谐波的估算式;举例分析了KDP三倍频方案中,基波位相畸变对二次谐波和三次谐波的影响;实验工作中,用哈特曼-夏克传感器分别对1064nm倍频过程和790飞秒超短脉冲倍频过程中的基波和谐波的位相分布进行了测量,给出了相应结果。

The research of making use of 2D image to form the 3D objects has been a field paid attention to very much all the time. In this work, we propose the synthetic way of a 3D human head, based on image information of multiple-view, cooperate with a Generic 3D head model. By choosing the feature points from images to estimation of position of the camera, and then dealing with information reconstruction of human head and feature point relationship between images and 3D object. Subsequently, applying interpolation technique, the head model is deformed from original model to fit the computed feature points by using Radial Basis Function. Make the form of the head model of people after deformation in conformity with true face of people. Finally, execute 3D head texture mapping and reach the function of translation and rotation with arbitrary direction.
利用二维影像来合成三维物件的研究一直是很受到重视的一个领域,在本论文中,我们提出一个三维立体人头的合成方式,以多张不同视角的影像资讯为基础,配合一个事先准备好的通用三维人头模型(generic 3D head model),透过二维影像中特徵点的选取来估算出拍摄的角度、方位,进而处理人脸模型五官的资讯重塑与特徵点对应的关系,接著利用内差技术,使用放射基底函数对三维通用人头模型作形变,使形变过后人头模型的形状与真实人脸相符,最后对三维通用人头模型作材质贴图,并可对此模型作任意角度、方向的旋转平移,以期达到类似照镜的功能。
