提出了一种单摄像机标定相移数字全息术。在该系统中，两种类型的信息被同时记录在一个单一的图像的基础上的空分复用技术。一种类型的信息用于重建对象图像，而另一种类型的信息用于计算相移量。由于该方法不需要任何附加的电子器件就能准确地检测相移量，因此可以研制出一种简单、低成本、高质量的相移数字全息再现系统。通过实验证明了该系统的有效性。
This paper proposes a calibrated phase-shifting digital holography by using a single camera. In the proposed system, two types of information are recorded simultaneously in a single image based on the space-division-multiplexing technique. One type of information is used to reconstruct the object image, while the other is used to calculate the phase-shifting amount. As the proposed method can detect the phase-shifting amount accurately without using any additional electronic devices, a simple low-cost high-quality image reconstruction phase-shifting digital holography system can be developed. The effectiveness of the proposed system is demonstrated through experiments.
