RGB laser diodes light up laser bean scanner for AR smart glasses

Sub-assembled RGB laser didoes by ams Osram are used to illuminate TriLite’s Trixel 3 laser beam scanner (LBS), which is the world’s smallest projection display, claims TriLite.

The Trixel 3 LBS is compact and lightweight with low power consumption of less than 320mW for all day use. It also has full colour support above 200 per cent over sRGB, for “excellent image quality”. Trixel 3 enables augmented reality (AR) for smart glasses and a range of consumer applications. 

Dr. Jörg Strauss, senior vice president and general manager business line visualisation and sensing at ams Osram, commented: “We are excited to partner with TriLite as Trixel 3’s compact design paves the way for widespread adoption of ‘always-on’ consumer AR glasses”. 

TriLite designs for seamless mass manufacturing, incorporating customised standard components. The compact optical display engine has a brightness of 15 lumens, ensuring effortless readability even in direct sunlight, said TriLite. Low system latency allows AR images to blend naturally with the wearer’s surroundings and movements, providing an immersive AR experience. Trixel 3 is compatible with the latest waveguides without requiring any relay optics, confirmed the company, to save space and reduce weight. 

Trilite’s compact and lightweight Trixel 3 LBS optical display engine combines a single 2D MEMS mirror, optical components and the trajectory control module (TCM). The LBS module weighs less than 1.5g and has a volume of less than 10mm3. 

TriLite designs and builds the world’s smallest projection displays for augmented vision lightweight enough for eyewear. The company’s display solutions are based on proprietary, multi-parameter algorithms and deploy advanced machine learning algorithms to generate laser beam scanning devices.

ams Osram specialises in intelligent sensors and emitters for customers in the automotive, industrial, medical and consumer markets. 

The company is headquartered in Premstaetten/Graz (Austria) with a co-headquarters in Munich (Germany).
