Two methods for obtaining a 3-D image are proposed, based on an adequate combination of the directivity properties of light diffracted by an oriented speckle pattern with the well-known stereovision requirements. Compatibility between an actual 3-D display and 3-D diffracted light distribution is reached in such a way that depth perception and a quasi-continuous variation of perspective are present. The analysis of several angular parameters involved is done to minimize some common limitations such as the flipping effect.
