    • A coherent radiation imaging system that produces digital images with a reduced amount of speckle. Radiation from a long coherence length source is used to form an image of a sample. The output coherent wave is temporally divided into a plurality of wavelets. The spatial phase of each wavelet is then modulated a known and different amount. Each phase modulated wavelet illuminates the sample and is perturbed by its interaction with the sample. A spatial phase map of each perturbed wavelet is then created and converted to a sample image with an image reconstruction program. The plurality of sample images thus formed is statistically averaged to form a final averaged image. The high frequency speckle that is not optically resolvable tends to average to zero with continual statistical averaging, leaving only the optically resolvable lower frequency phase information.
    • 相干辐射成像系统,产生数量少的斑点数字图像。 来自长相干长度源的辐射用于形成样品的图像。 输出相干波在时间上分为多个小波。 然后将每个小波的空间相位调制为已知且不同的量。 每个相位调制小波照亮样品,并受到与样品的相互作用的干扰。 然后创建每个扰动小波的空间相位图,并将其转换为具有图像重建程序的样本图像。 如此形成的多个样本图像被统计学地平均以形成最终平均图像。 不能光学解析的高频散斑趋向于平均为零,并且连续的统计平均,仅留下光学可分辨的较低频率相位信息。
