A 3D stereoscopic head‐up display using a tunable bandpass filter to perform left and right image spectral separation is presented. Using a single filter reduces the size and the cost of the head‐up display optical engine and enables each spectral band to be accurately tuned. Experiments performed on the first prototype demonstrate the ability to continuously tune the bandpass frequency on 30‐nm range while keeping a 20‐nm bandwidth. Such a system avoids the use of a bulky and costly rotating wheel and enables the use of holographic optical elements known to be wavelength selective.
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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
