59‐2: Distinguished Paper: Development of a 3D HUD using a Tunable Bandpass Filter for Wavelength Multiplexing

Abstract

A 3D Stereoscopic Head‐Up Display (HUD) 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 HUD optical engine, and enables each spectral band to be accurately tuned. Experiments performed on the first prototype demonstrates 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.
