To realize high speed parallel processing, parallel optoelectronic computing system which has processing element (PE) and optical interconnection between PEs is one of effective methodologies. In this research we construct high speed massively parallel processing system with our original PE by electronic circuit and optical interconnection experimentally, and realize some meaningful operations by the system.To construct the system actually, we arranged the needed specification for each elementally tchnology, and decided the algorithms to make it work. And we reexamined the performance of each elementally technology, and obtained the fundamental data for the improvement. Therefore the limitation in present technology and the predictin of the performance in future are explicit.In fact, we made 16*16 PE array using LSI,and developed the alorithms to execute on it. Measuring the actual performance of computer generated hologram (CGH), we obtained the fundamental data to improve.Especially we specified optical devices (emitting detector array, photo detector array, spatial light modulator (SLM), high resolution display, et.al.) to satisfy our request. As a result we found the writing time to liquid crystal spatial light modulator is the neck of system.Developing the processing element and the algorithms, we paid attention to the analysis of the algorithms which consider optical interconnection.In order to correspond to the wavelength of the surface emitting laser diode array (VCSEL) using as emitting elements, we changed the wavelength of optical device contains SLM,However we obtained good experimental results.

并行光电计算系统是实现高速并行处理的有效方法之一，它具有处理单元和处理单元之间的光互连。在本研究中，我们利用我们原来的PE，通过电路和光互连实验构建了高速大规模并行处理系统，并通过该系统实现了一些有意义的操作；为了真正构建该系统，我们为每个基本技术安排了所需的规范，并确定了使其工作的算法。并重新考察了各基本技术的性能，为改进提供了基础数据。实际上，我们用LSI制作了16×16 PE阵列，并开发了在其上执行的算法。通过对计算全息图的实际性能进行测量，得到了需要改进的基础数据，特别是对光学器件(发光探测器阵列、光电探测器阵列、空间光调制器、高分辨率显示器等)进行了详细的描述。来满足我们的要求。结果发现，写入液晶空间光调制器的时间是系统的瓶颈。在开发处理单元和算法时，重点分析了考虑光互连的算法。为了与作为发射元件的表面发射激光二极管阵列(VCSEL)的波长相对应，我们改变了含有SLM的光学器件的波长，但得到了良好的实验结果。
