包括相位不连续性的一般光场的无偏（无参考）相位场成像
Unbiased (reference-free) phase field imaging for general optical fields including phase discontinuities
摘要：
本文提出了一种新的测量局域电光场及其相位的方法。该方法是基于自参考干涉图（SRI），如剪切干涉图。复电场是以像素分辨干涉项E_2* E_1为参数的线性方程的解向量。非线性方程组的线性化是通过使用由常规图像检测器获得的强度的先验知识来实现的。所得到的线性方程不是基于任何近似，迭代摄动展开等，但精确。该方法是非迭代和稳定的对任意选择的测试字段的噪音。允许的场可以在像素尺度上表现出高度波动的幅度/相位、幅度消失的区域和Pi相位跳跃。空间分辨率为像素大小。不使用参考光束和光阑。新方法可以实现为快速的、每帧一次拍摄的视频系统。对非经典双光子态（包括真空压缩相干态）的空间分辨测量作了展望。
英文摘要：
A new numerically and experimentally tested measurement method for the local electrical light field including its phase is presented. The method is based on Self Referencing Interferograms (SRI) such as shearing interferograms. The complex electric field is the solution vector of a linear equation with the pixel resolved interference term E_2* E_1 as a parameter. Linearization of the non linear equations is achieved by using preknowledge in the intensity as obtained by a conventional image detetctor. The resulting linear equations are not based on any approximation, iterative perturbation expansion etc. but are exact. The method is non iterative and stable against noise for arbitrarily chosen test fields. Allowed fields can exhibit highly fluctuating amplitudes/phases on the pixel scale, areas of vanishing amplitude and Pi phase jumps. The spatial resolution is of pixel size. No reference beam and no diaphragms are used. The new method can be implemented as a fast, one shot per frame video system. An outlook on the space resolved measurement of non classical two photon states (including vacuum squeezed coherent states) is given.
