50-3: A Full Windshield Head-Up Display using Simulated Collimation

Abstract

A 3D Stereoscopic Head‐Up Display (HUD) using direct projection on a transparent screen is presented. Symbol incrustation on the real world (Augmented Reality) is performed by using simulated collimation offering a large eye‐box, in excess of conventional HUD. Experimentation performed on this system shows that Accommodation‐Vergence issues, occurring when looking outside while reading on a foreground screen can be acceptable for a screen distance greater than 60 cm, and comfortable from 1.7 m.

Improving head-up display with waveguides and holographic optical elements

“…[7][8][9][10][11][12] The choice of relay optics in the system can locate the projected symbology in the observer's far field. 13,14 This display system presents relevant control information to the vehicle's operator, while still allowing light from beyond the combiner to propagate to the observer.…”

Holographic waveguide heads-up display for longitudinal image magnification and pupil expansion

“…By overlaying relevant flight data on the real-world scene outside the plane, pilots are saved from having to redirect their gaze from the exterior of their vehicle to see the information on the HDDs [3][4][5]. HUDs designed for aviation locate their projected flight symbols in the far field [6,7]. This means that observers need not change their focus away from their environment to see the information presented by the HUD.…”
