An extremely simple setup for real-time color digital holography using single-mode fibers as light guides and a directional coupler as a beam-splitting device is presented. With the directional coupler we have two object beams and one residual crosstalk used as a reference beam. This facilitates the adjustment and improves robustness. With the use of graphics processing units, real-time hologram reconstruction was possible. Due to adaptation of the optical setup and scaling, zero-order and complex image influence is highly reduced.
本文提出了一种极其简单的实时彩色数字全息术设置，该设置使用单模光纤作为光导，并使用定向耦合器作为分束装置。通过定向耦合器，我们有两束物光和一束用作参考光的残余串扰光。这便于调整并提高了鲁棒性。通过使用图形处理单元，可以实现实时全息图重建。由于对光学设置的调整和缩放，零阶和复像的影响大大降低。
