Abstract

A light projector () for an augmented reality headset is disclosed. The light projector includes an image generator () configured to provide an image with unpolarised light and a beam splitter () configured to receive unpolarised light from the image generator and to split it into a first path and a second path. A first optical arrangement is configured to receive light from the beam splitter in the first path so that light is reflected, focused and directed back towards the beam splitter. A second optical arrangement configured to receive light from the beam splitter in the second path so that light is reflected, focused and directed back towards the beam splitter, wherein the first and second optical arrangements comprise first and second mirrors () respectively. The beam splitter is configured to receive and combine light from the first and second optical arrangements so that the combined light, which unpolarised, is provided to an exit pupil, and the first and second optical arrangements are angled relative to one another so that the image from the first path is aligned with the image from the second path.
