Development of a real-time recording and reconstruction system for moving 3-D images using electronic holography

我们研制了一种利用高功率脉冲激光实时记录复振幅全息图的全息摄像机。我们还通过将全息摄像机连接到我们的全息显示系统，开发了实时3D显示系统。我们已经展示了实时记录和重建的室内照明下移动的3-D图像。利用高功率脉冲激光在日光下记录全息图是可能的。通常的个人计算机从记录的离轴全息图生成一个全息图的计算时间短于30毫秒。该显示系统的帧速率受到相机链路图像传感器的性能的限制。

We have developed a holographic video camera using a high-power pulsed laser for real-time recording of complex-amplitude holograms. We have also developed a real-time 3-D display system by connecting the holographic video camera to our holographic display system. We have demonstrated real-time recording and reconstruction of moving 3-D images under room lighting. It is possible to record holograms under daylight using a high-power pulsed laser. Calculation time by a usual personal computer is shorter than 30 msec to generate one hologram from a recorded off-axis hologram. Frame rate of this display system is limited by the performance of camera-link image sensor.
