Microlens array-based high-gain screen design for direct projection head-up displays.
Head-up display (HUD) systems have been used in recent car models to provide essential information to the drivers while keeping their eyes on the road. Virtual image HUD systems have been the preferred method, but they have the drawback of requiring a large volume of space in order to accommodate the relay optics that creates the virtual image. This is especially significant as the desired fiel...
متن کاملImplementing Laser Scanned-MEMS Projection in Automotive Head-Up Displays
In 1988, the Oldsmobile Cutlass Supreme became the first production car with a basic head-up display, also known as HUD. Automotive safety was and continues to be the main driving force for the deployment of HUDs with the aim of preventing drivers from taking their eyes off the road to look down and read their dashboard instruments. Distracted driver studies have shown that taking your eyes off...
متن کاملProjection-based head-mounted displays for wearable computers
The projection based head-mounted display (HMD) constitutes a new paradigm in the field of wearable computers. Expanding on our previous projection based HMD, we developed a wearable computer consisting of a pair of miniature projection lenses combined with a beam splitter and miniature displays. Such wearable computer utilizes a novel conceptual design encompassing the integration of phase con...
متن کاملTransmission characteristics of a bidirectional transparent screen based on reflective microlenses.
A microlens array (MLA) based see-through, front projection screen, which can be used in direct projection head-up displays (HUD), color teleprompters and bidirectional interactive smart windows, is evaluated for various performance metrics in transmission mode. The screen structure consists of a partially reflective coated MLA buried between refractive-index-matched layers of epoxy as reported...
متن کاملA high numerical aperture, polymer-based, planar microlens array.
We present a novel microfabrication approach for obtaining arrays of planar, polymer-based microlenses of high numerical aperture. The proposed microlenses arrays consist of deformable, elastomeric membranes that are supported by polymer-filled microchambers. Each membrane/microchamber assembly is converted into a solid microlens when the supporting UV-curable polymer is pressurized and cured. ...
