Abstract
We combine the concept of reduced spatial coherence, as discussed in [1], with a specialized microstructure of the screen material. When the screen is an array of microlenses, the interference between the fields emitted by different lenses in the array (the cause for cause for speckle) can be inhibited by reducing the on-screen spatial coherence area to below the microlens footprint. In this approach we also have to ensure that this footprint is smaller than the observer’s resolution spot on the screen. Otherwise, we risk resolving the individual lenses of the array in the observed image, thereby reducing the image quality. These two criteria are visualized in Fig.1.
