With the rise of video games, entertainment, and online meetings, augmented reality is widely used in the creative industries. Especially after the outbreak of the new crown pneumonia epidemic, online meetings and online courses with social networks in education, medical care, industry and other fields have developed rapidly, providing broad prospects for the application of AR glasses. 

At the same time, optical system testing: Thanks to optical waveguide devices in microdisplays and AR glasses, AR technology is advancing with each passing day, image quality is better, and wearables are lighter in weight. Augmented reality wearables such as smart glasses enable users to see images generated by the virtual world.

With the breakthrough of AR in the field of mobile technology, capital investment in the market has promoted the research and mass production of different AR glasses products. In the consumer market, we can see new products being released all the time. AR glasses OEMs need to compare the specifications of each product side-by-side, and they are also interested in knowing the nominal parameters of the imaging quality of similar products.

We have heard that AR glasses are needed in many cases to measure eyebox, line-of-sight, FOV, and image distortion because customers want to validate their product specifications to see if the DOE provided by the supplier can meet the imaging results provided by the actual specifications. Therefore, optical waveguide design components are an important part of the evaluation of the display image of augmented reality glasses.

Optical waveguides are widely recognized as one of the promising ways to enable affordable augmented reality (AR)/mixed reality (MR) devices, which, combined with small-scale image quality, can provide a fully immersive user experience. Multiple optical structures – waveguides, reflective beam combiners and beam splitters can be used to make AR wearable devices. Each architecture has different advantages in terms of appearance (size and weight),
