    • A method and system are provided, for imaging a region of interest with pinhole based imaging. The method comprising: collecting input radiation from the region of interest through a selected set of a plurality of a predetermined number of aperture arrays, each array having a predetermined arrangement of apertures and collecting the input radiation during a collection time period, wherein said selected set of the aperture arrays and the corresponding collection time periods defining a total effective transmission function of the radiation collection, generating image data from the collected input radiation, said image data comprising said predetermined number of image data pieces corresponding to the input radiation collected through the aperture arrays respectively, processing the image data pieces utilizing said total effective transmission function of the radiation collection, and determining a restored image of the region of interest. The set of aperture arrays is preferably selected such that said total effective transmission function provides non-null transmission for spatial frequencies being lower than a predetermined maximal spatial frequency.
    • 提供了一种方法和系统,用于利用针孔成像来成像感兴趣的区域。 该方法包括:通过选定的多个预定数量的孔阵列收集来自感兴趣区域的输入辐射,每个阵列具有预定排列的孔,并在收集时间段收集输入辐射,其中所述选定的组 并且相应的收集时间段定义了辐射采集的总有效传输功能,从收集的输入辐射产生图像数据,所述图像数据包括与通过孔收集的输入辐射对应的所述预定数量的图像数据片段 分别利用所述辐射采集的所述总有效传输功能处理所述图像数据片段,以及确定所述感兴趣区域的恢复图像。 优选选择一组孔径阵列,使得所述总有效传输功能为空间频率低于预定最大空间频率提供非零传输。
