我们提出了一种基于空间相干门原理的混浊介质成像新电子显微镜系统，该系统无需扫描即可并行生成完整的二维正面图像。该系统已在商业显微镜中实现，并保留了所用光学器件的横向分辨率。利用空间非相干源，在连续深度处记录具有衍射限制分辨率的无散斑图像，并进行散粒噪声限制检测。该装置包括用于路径差调制的光弹性调制器和二维CCD阵列，并使用多路锁定检测方案。(C)1998年美国光学学会。
We present a nem microscopy system for imaging in turbid media that is based on the spatial coherence gate principle and generates in parallel a complete two-dimensional head-on image without scanning. This system has been implemented in a commercial microscope and preserves the lateral resolution of the optics used. With a spatially incoherent source, speckle-free images with diffraction-limited resolution are recorded at successive depths with shot-noise-limited detection. The setup comprises a photoelastic modulator for path difference modulation and a two-dimensional CCD array and uses a multiplexed lock-in detection scheme. (C) 1998 Optical Society of America.
