    • The invention relates to a display for the holographic reconstruction of a three-dimensional scene using means which allow a reduction of speckle patterns. Speckle patterns result in the graining of a holographic reconstruction and worsen the quality thereof. Various means for solving the problem have been proposed, by which, in accordance with the basic idea of the invention, the 3D scene is incoherently superimposed with itself chronologically or spatially in the eye of the observer. The modulated wave fronts of each reconstructed object point of the scene are shifted relative to themselves in the reconstruction beam path and superimposed in the eye of the observer by these means. The shifting may occur one-dimensionally and two-dimensionally. Each object point is multiplied with itself in the eye of the observer in accordance with the number of the shifted wave fronts. With the multiplication of all reconstructed object points, the various speckle patterns over which the eye of the observer averages are also multiplied. Speckle patterns are reduced and the reconstruction quality is thus increased according to the invention in holographic displays.
    • 本发明涉及使用允许减少斑纹图案的装置的三维场景的全息重建显示器。 斑点图案导致全息重建的粗糙化,并使其质量恶化。 已经提出了用于解决问题的各种手段,根据本发明的基本思想,3D场景在观察者的眼睛中与时间顺序或空间上不相干地叠加。 场景中每个重建对象点的调制波前相对于自身在重建光束路径中移动,并通过这些方式叠加在观察者的眼睛中。 移位可以一维和二维地发生。 根据移动的波前面的数量,每个物点在观察者的眼睛中与其自身相乘。 随着所有重建对象点的乘法,观察者平均眼睛的各种斑纹图案也相乘。 根据本发明,全息显示器中的散斑图案减少并因此提高了重建质量。
