Biocular vehicle display optics is a fast collimating lens (f / # < 0.9) that presents the image of the display at infinity to
both eyes of the viewer. Each eye captures the scene independently and the brain merges the two images into one
through the overlapping portions of the images. With the recent conversion from analog CRT based displays to lighter,
more compact active-matrix organic light-emitting diodes (AMOLED) digital image sources, display optical designs
have evolved to take advantage of the higher resolution AMOLED image sources. To maximize the field of view of the
display optics and fully resolve the smaller pixels, the digital image source is pre-magnified by relay optics or a coherent
taper fiber optics plate.
Coherent taper fiber optics plates are used extensively to:
1. Convert plano focal planes to spherical focal planes in order to eliminate Petzval field curvature. This
elimination enables faster lens speed and/or larger field of view of eye pieces, display optics.
2. Provide pre-magnification to lighten the work load of the optics to further increase the numerical aperture
and/or field of view.
3. Improve light flux collection efficiency and field of view by collecting all the light emitted by the image source
and guiding imaging light bundles toward the lens aperture stop.
4. Reduce complexity of the optical design and overall packaging volume by replacing pre-magnification optics
with a compact taper fiber optics plate.
This paper will review and compare the performance of biocular vehicle display designs without and with taper fiber
optics plate.
