چکیده

It is difficult to design and fabricate a head-up display (HUD) with a large asymmetric field of view (FOV) while maintaining a good image quality. In this paper, we design and develop such a holographic HUD system. To improve luminance and enhance the environmental adaptability of the HUD, we use a liquid crystal display with high brightness as well as a holographic reflection element. The vertical FOV is tilted to an angle of -7°, which is consistent with the actual view of the pilot. The decentration and tilt of the optical relay system effectively compensate for the distortion and off-axis aberration due to the asymmetric FOV and tilted, curved combiner. The transition plates used in the mechanical structure significantly decrease the difficulty in fabrication and alignment, and virtual prototyping greatly reduces the risk and shortens the development cycle. Experimental results demonstrate that this prototype achieves a total FOV of 30° (horizontal) ×24° (vertical), a resolution of 1280×1024, and a 5% distortion.

Optical Modeling of a Holographic Single Element Head-mounted Display

This paper proposes a new method to design an optically-fabricated holographic element, where the construction optical system and the playback system can be optimized jointly. The method was driven by the use of a new holographic recording material – the photo-thermo-refractive (PTR) glass that can only be written at 325nm, while its playback takes place in the visible part of the spectrum. App...

A Polarization-selective Module for Dense Magneto-optical Pick-up Heads

A polarization-selective holographic optical element with compact dimensions of 2.4mm X 1mm X 1mm (width X length X thickness) is proposed. The element includes three modules: a holographic polarizing beam-splitter, a holographic input coupler, and a dove-prism coupler so that a simple and dense optical pick-up head can be achieved. Polarization properties of holographic volume gratings are bri...

Very Large Format Stereoscopic Head-Up Display for the Airport Tower

Head-up displays typically used in aircraft and automobiles have limited fields of view, generally less than 30◦. Such systems can provide large, essentially unlimited fields of regard if they are head-mounted. A new alternative for provision of large fields of regard without requiring a head mount is a large format holographic optical element that can serve as a see-though polarization preserv...
