The system combines TriLite’s Trixel 3 laser beam scanner (LBS) with Dispelix’s advanced waveguides.
For AR glasses, the image creation system requires a projector, such as Trixel 3, as well as a waveguide, which is a predominately transparent, thin piece of glass or plastic that bends and combines light beams from multiple sources into the eye.
According to TriLite, the Trixel 3 is the world’s smallest LBS projector, with a volume of less than 1cm3 and ultra-light weight of 1.5g. The module enables comfortable long-term wear and doesn’t require any additional relay optics between the LBS projector and the waveguide, which typically doubles the size of systems in many other products.
The combined system form factor with Dispelix’s ultra-thin waveguide is said to be one of the most compact achieved and means that AR could now be possible in every pair of glasses, regardless of size or style.
Commenting Peter Weigand, CEO at TriLite, said: “Our collaboration will result in some of the thinnest, lightest and highest-performing AR consumer devices on the market.”
In addition to the system’s small size, another benefit from the collaboration is that TriLite’s high brightness LBS supports the large eyebox of Dispelix waveguides. This projection system can generate the high brightness required even for extreme outdoor usage.
The large eyebox eliminates the need for custom adjustment and fitting of AR smart glasses, ensuring a much crisper crisp image regardless of who is wearing the glasses.
