9319211潘本提案要求对扫描全息术和3-D图像编码的基本和应用方面的研究进行研究。 该项目是主要研究者以前工作的延续，沿着使用光外差扫描的实时全息记录技术。 简言之，在该技术中，使用不同时间频率的两个光束来扫描物体以提取物体的全息信息。 在目前提出的研究中，我们调查和比较的相干，部分相干和不相干的扫描全息信息减少技术，3-D编码和多重曝光全息的性质进行了探索，并扩展到多个全息信息的对象同时。 多波束扫描的优点包括实时操作和大的复用能力。集成的电子束寻址的空间光调制器的相干重建与扫描全息记录系统也被研究在视频速率的真实的时间全息的上下文中。 拟议工作的结果可能导致更好的三维信息处理和编码，例如在实时三维图像处理、显微镜、数据存储和获取以及光学遥感等领域。

9319211 Poon This proposal requests for a research program on the study of the basic and applied aspects of scanning holography and 3-D image coding. The projects is a continuation of the principal investigator's previous work along the line of real-time holographic recording technique using optical heterodyne scanning. Briefly, in the technique, two optical beams of different temporal frequencies are use to scan an object to extract the holographic information for the object. In the present proposed research we investigate and compare the coherent, partial coherent and incoherent nature of the scanning holographic information reduction techniques, 3-D coding and multiple-exposure holography are explored and extended to multiple holographic information of the object simultaneously. Advantages of multiple-beam scanning includes real-time operation and large multiplexing capability. The integration of an electron-beam-addressed spatial light modulator for coherent reconstruction with the scanning holographic recording system also is investigated in the context of real time holography in video rate. The results of the proposed work could lead to better 3-D information processing and coding such as in the areas of real-time 3-D image processing, microscopy, data storage and acquisition and optical remote sensing.
