Brighter, Larger, More Efficient AR Displays with Luminit THCs

06 Dec 2018

Luminit is blazing a new path for augmented reality displays in the automotive, avionics and wearables industries with Transparent Holographic Components (THCs). Designed for heads-up, helmet-mounted, or near-to-eye AR/VR display systems, Luminit THCs provide display brightness that is up to 10 times higher than conventional systems due to highly efficient holographic optical elements that direct light beams without the need for expensive and bulky optics. Made with a thin (16-micron) photopolymer recording media, Luminit THCs use advanced holographic designs to replace traditional bulky optics with a thin lightweight clear film component. The holograms recorded in this film have properties of “volume” (Bragg) holograms that can provide optical power and perform both lens and/or mirror functions. THCs are wavelength and angularly selective with very low scattering that can achieve transparency above 90% and high diffraction efficiencies of up to 80%.

Benefits include:

• More efficient product design
• Larger virtual image distances
• Reduced weight and more flexibility in packaging design
• Reductions in power consumption due to increased optical efficiency

THC for Heads-up Displays and Wearables

This holographic optical element performs well on wearable technology such as augmented reality smart glasses and virtual reality headsets. For helmet mounted designs, THCs can provide off-axis image projection of high-resolution micro-displays through a thin plastic visor. For smart glasses, THCs eliminate prism-based optics with a see-through technology that allows the images to be viewed at arms-length (or further) virtual distances without added weight to the user.

THCs for Automotive

When combined with an automotive grade picture generation unit (PGU), Luminit THCs can produce floating, transparent virtual images at distances that don’t distract drivers or require them to lose focus on the road. Other uses for THCs in automobiles include hiding a light source, such as interior dome

lights or center high mount stop light (CHMSL) on the rear windshield. Luminit THCs can also be used for branding purposes, such as floor lights or mud lights that project light (e.g., auto manufacturers’ logos) onto surfaces.

Mass Production Capabilities

Luminit’s unique production capabilities allow roll-to-roll optical reproduction of volume holograms and surface relief films. THCs are scalable; have a compact, lightweight form factor; and can be mass produced in the tens of thousands.
