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杂振幅全息图的全息摄像机。我们还开发了一个实时三维显示系统，将全息摄像机连接到我们的全息显示系统。我们已经演示了在室内照明下实时记录和重建移动的三维图像。利用大功率脉冲激光在日光下记录全息图是可能的。用普通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小于30毫秒。该显示系统的帧率受到摄像机链路图像传感器性能的限制。

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.
