| 摘 要： | 本文将数字微镜（DMD）应用于数字全息,提出了一种新的实时再现方法,该方法用CMOS采集全息图,经计算机编程处理后直接输送到DMD,经激光照射后实时再现物光场的干涉像,取代了以往数字全息中用计算机编程衍射计算实现干涉像再现的过程,达到了节省时间,实时观察的目的。文章以温度场检测为例,将DMD再现的干涉像与计算机衍射计算再现的结果进行了对比,证明了该方法的可行性和准确性。

| Abstract: | DMD is used in digital holography as a new reconstruction method.The real time reconstructed image can be obtained by illuminating the digital hologram which is recorded by CMOS and then transmitted into DMD.It shortens the reconstructed time and completes the real time observing.After being compared the reconstruction results of temperature field obtained by DMD and diffraction calculation,it is proved that the new-method is feasible and accurate. |
