用模拟的和实验的扫描相干衍射显微镜数据对平面迭代引擎（PIE）算法进行了检验。利用模拟衍射数据确定了在图像质量、样品剂量和测量时间方面的最佳重叠。实验氦氖激光衍射数据支持了结果的有效性。(c) 2007 Elsevier B.V.版权所有
The ptychographical iterative engine (PIE) algorithm is examined with both simulated and experimental scanning coherent-diffraction microscopy data. The optimum overlap in terms of image quality, dose on the sample and time of measurements is determined using simulated diffraction data. The validity of the results is supported by experimental helium neon laser light diffraction data. (c) 2007 Elsevier B.V. All rights reserved.
