Abstract

Holographic displays based on spatial light modulators suffer from limited ´etendue, defined as the product of the display’s size and angular range and bounded by the number of pixel units. In this work, we suggest that rather than excessively increasing the pixel count, etendue can be expanded by augmenting the display units with tilting capabilities. We built a prototype constructed of multiple binary tilt layers and demonstrated applications of the device.
