For the HUD virtual image, the projected distance distribution functions are presented, for two selected patches in the FOV (Area 1 and 2). These are well described by Gaussians. As representative values, we obtained a mean projected distance of 0.15 ± 0.02 (horizontal details) and 0.03 ± 0.02 (vertical) Diopters, for Area 1, and 0.33 ± 0.04 (horizontal) and 0.03 ± 0.02 (vertical) Diopters, for Area 2. The estimated astigmatism is 0.12 and 0.30 Diopters, for Areas 1 and 2, respectively. When expressed in meters, the projected distances are 7 1 (horizontal) and 28 9 (vertical), for Area 1, and 3.1 ± 0.4 (horizontal) and 30 ± 10 (vertical), for Area 2. The estimated astigmatic difference is 21 and 23 meters, for Areas 1 and 2, respectively. |
