Abstract:
A head mounted display device includes a light source that emits a high coherence light beam, a beam expansion/diverging element that expands the light beam emitted by the light source, and a beam converging element that converges the expanded light beam into a viewing zone. The light beam from the beam converging element is incident onto a spatial light modulator (SLM), and the SLM is configured to add a phase pattern and/or an amplitude pattern to the light beam to generate a virtual image that is visible to a user wearing the head mounted display device. The light converging element creates a beam or scanning beam axis that converges towards the eye, which enables a large field of view for a virtual or holographic image to be displayed.
