Random phase-shifting digital holography based on a self-calibrated system is proposed. In the proposed method, the hologram and the calibration interference fringes can be recorded simultaneously in a single image based on the space-division-multiplexing technique. Three randomly phase-shifted holograms and corresponding interference fringes are recorded, and the phase-shifting amount between each two adjacent holograms is calculated by the sampling Moiré method from the calibration interference fringes. A reflective object is used to demonstrate the effectiveness of the proposed method in the numerical and experiment.
提出了一种基于自校准系统的随机相移数字全息术。在所提出的方法中,基于空分复用技术,全息图和校准干涉条纹可以同时记录在单个图像中。记录三个随机相移的全息图及其相应的干涉条纹,并通过采样莫尔法从校准干涉条纹中计算出每两个相邻全息图之间的相移量。使用一个反射物体在数值和实验中验证了所提方法的有效性。
