Abstract
Light Blue Optics’ holographic laser projection technology is uniquely suited as a light engine for automotive head-up display (HUD) applications, providing high brightness images with low speckle contrast and wide colour gamut whilst being robust and fault-tolerant. This paper describes the operation of the technology and its advantages, demonstrating – for the first time – the operation of a full-colour, laser-based automotive HUD which is capable of displaying both symbology and night vision virtual imagery. The ability of the projector to correct for distortion introduced by the windshield curvature is demonstrated, showing significant progress towards a ‘one-size-fits-all’ HUD.
