像ltv - slm这样的矩阵寻址液晶显示器件是电全息系统的重要器件之一。在该系统中，CCD摄像机读取全息干涉条纹图，并将其信号通过视频信号线传输到lcd - slm。LCTV-SLM作为一种动态全息装置工作。在重建过程中，采用空间滤波技术去除零级衍射光。对振幅型全息图和相位型全息图进行了比较，并对白光全息图进行了重建。还讨论了细像素液晶显示器的可能性。
A matrix-addressed liquid crystal display device like LCTV-SLMs is one of the important devices for our electro-holography system. In this system, a CCD camera reads holographic interference fringe pattern and its signal is transferred to the LCTV-SLM by video signal line. The LCTV-SLM works as a dynamic holography device. A spatial filtering technique is applied to remove zero-order diffracted light on reconstruction. A comparison between amplitude-type and phase-type holograms and reconstruction by white light are described. The possibility of fine-pixel LCDs are also discussed.
