我们在3D显示器上进行了一项实验，采用了空间交叉调制(SCM)，使用了随机漫射器和纯相位空间光调制器(SLM)。在我们的实验中，生成了一个3D对象，该对象是由从不同空间位置获取的四幅2D图像构建的，然后将编码后的3D对象显示在SLM上。当图像传感器移动到不同的空间位置时，观察到不同的对象图像。实验结果表明，SCM方法可以产生高衍射效率、几乎没有散斑噪声的任意复幅值场。
We performed an experiment on a 3D display by employing spatial cross modulation (SCM) using a random diffuser and phase-only spatial light modulator (SLM). In our experiment, a 3D object, which is constructed using four 2D images acquired from different spatial positions, is generated and the encoded 3D object is then displayed on the SLM. The different object images are observed when the image sensor is moved to different spatial positions. The experimental results revealed that the SCM method allows the generation of arbitrarily complex amplitude fields with high diffraction efficiency and with almost no speckle noise.
