Luminit Transparent Holographic Components (THCs) are creating new opportunities for Head-mounted, Vehicular and Avionics Head-up Displays. These lightweight and highly efficient components use holographic optical elements to direct light without the need for bulky conventional optics. Compact form factors (<1.5 liters) are possible that can fit easily within under-dash or combiner designs. These holographic beam diffractive diffusers can be customized to accommodate HUD virtual image distances of 1-meter or farther and work for visible (RGB) to IR wavelengths. Advantages of transparent holographic optical elements include:
Unparalleled transparency above 90%
High diffraction efficiency above 80%
Bright virtual images that can be projected in front of vehicles for increased safety
Luminit Transparent Holographic Components can be mass produced in high-volumes
THC for Heads up Displays and Wearables
This optical diffuser performs well on heads-up displays for pilots and motorcyclists as well as wearable technology such as smart glasses, augmented reality (AR) and virtual reality (VR). For helmets, THC possibilities include head-mounted displays for off-axis image projection of a high-resolution micro-display through a thin plastic visor. For smart glasses, THC eliminates prism-based optics with fully see-through technology that allows the images to be viewed at a virtual distance without added weight to the user.
Transparent Holographic Components for Automotive
When combined with an LED light source, Luminit THC can produce a floating, transparent image on a car windshield without any obstruction of view. Other uses for THC in automobiles include hiding a light source, such as interior dome lights or center high mount stop light (CHMSL) on the rear windshield. Luminit THC can also be used for in branding purposes, such as floor lights or mud lights that can project light as well as the auto manufacturer’s logo.
Applications for Luminit’s Transparent Holographic Components:
- Solar concentrators
- Optical sensors
- High capacity recording memory
