Beschreibungen/Notizen
The Maxwellian display presents always‐focused images to the viewer, alleviating the vergence‐accommodation conflict (VAC) in near‐eye displays (NEDs). However, the limited eyebox of the typical Maxwellian display prevents it from wider applications. We propose a large FOV holographic Maxwellian display system and develop a new eyebox expansion method simultaneously. The system utilizes the special structure of the grating to provide secondary diffraction of the reconstructed image. The lens behind the grating is able to converge the reconstructed images of different diffraction orders at certain intervals of the point of view, which realizes a large FOV and extends the exit pupil size at the same time.
