摘　　要：波前重建(全息)是新型高分辨率动态三维显示技术的一种实现方式。空间带宽积是制约三维波前重建图像的视角范围、图像清晰度和尺寸等感知参数的重要物理因素。三维显示器件空间带宽积的扩展主要依赖像素尺度的微型化和显示屏幕的大型化。针对波前重建空间带宽积的扩展,在电-光调制器件方面,研究全相位调制LCo S器件像素微型化的新方法,通过分析液晶分子预倾角、像素单元介质薄膜、有序纳米结构对像素单元空间场强的影响,优化像素单元电场分布,为克服像素微型化带来的尺度效应提供理论依据。在像素单元CMOS电路方面,分析像素单元存储电容和负载电容的尺度效应及关联性。揭示硅基液晶LCo S等效电容尺度极限效应的物理机理。研究高迁移率非晶氧化物TFT材料,探索制备微米尺度像素阵列的新方法;通过超厚电极层等新工艺和铜合金等新材料的研究,为大尺寸显示器件的制备提供技术支撑。提出大尺寸、高效TFT阵列双边驱动新方法,解决电-光调制器件驱动提升的难题,突破微型化像素低压驱动的关键技术。在光-光调制器件方面,建立全息像元的空间带宽积理论模型,通过针对光折变材料的动力学机制开展研究,突破全息像元的角度、波长、偏振与相位复用关键技术,在光折变材料中实现多维复用记录和波前重建三维显示。基于以上的研究目标及内容,该年度的完成情况如下:(1)完成了ECB、VA两种液晶排列方式下的相位和振幅调制特性的研究;建立了双缝干涉法相位测试平台,掌握相位调制特性测试方法;(2)采用comsol和TechW iz软件建立了微型化液晶像素单元理论模型,实现液晶动态响应过程的模拟仿真;针对微型化像素,研究了有序纳米结构对空间电场分布的影响和优化;(3)获得掺W元素对IZO结构和特性影响的基本规律,获得铜合金电极薄膜制备�Wave front reconstruction （holography） is one of the techniques which can display high resolution, real-time 3D information. Space-bandwidth product is the key parameter for viewing angle, image sharpness and reconstruction size. The extension of space-bandwidth product relays on miniaturization of pixels and enlargement of display screens. For extension of space-bandwidth product, we research on two types of devices, electro-optical modulator and optical-optical modulator. For the former, research is on phase-only LCoS, it is expected to provide basic theories of reducing the size effect accompany with miniaturization of pixels by optimization of the influences of liquid crystal pre-tilt angle, dielectric membrane, and aligned nano-structure on electrical field of pixel cells. For CMOS circuits, the size effect and connections between storage capacitance and load capacitance is analyzed. The mechanism of equivalent capacitance size limitation effect of LCoS is revealed. Amorphous oxide TFT with high mobility ratio is researched to explore new method to fabricate micron pixel array. Technical support for fabrication of large size display device is provided by research on new technology of ultra-thick electrode layer and new material like copper alloy. It is expected to propose large size and high efficient TFT array double-side driving scheme, solve the driving promotion problem of electro-optical modulator and master the key technology of low voltage driving of miniaturization of pixels. For the latter, theoretical model of hogel space-width product is built. Based on research on dynamic mechanism of photorefractive material, it is expected to make breakthrough on key techniques on multiplexing of angle, wavelength, polarization and phase. So that multiplex recording can be used for photorefractive material for 3D wavefront reconstruction. Based on the research goals and contents above, the work we have completed is as following：（1）Characterization of phase and amplitude modulation of liquid crystal in
