Read Abstract +

Augmented reality (AR) displays have been a hot topic for many years as they offer potential for a high return on investment. With this high potential come many technical challenges to be addressed before AR displays and smart glasses become more accepted in the marketplace. One of the technical challenges is the optical design of compact and lightweight optics capable of projecting an augmented image onto the user line of sight with comfort. Major advances are being made in waveguide technology to produce large FOV and eye-box. Equally, light engines are also being developed to be less bulky and more efficient. In this paper we present an insight on how a next generation laser beam scanner (LBS) developed by TriLite Technologies can be integrated with different combiners and implemented for different AR displays and smart glasses architectures. The unique design of the LBS lends itself to fit in different configurations as dictated by the different designs and layouts of waveguide and combiners. In addition, the extremely low profile of the next generation LBS make the glasses look smart literally.
