Abstract

We present our latest developments and results in making masters for replication of surface relief waveguides. Accurate control of the diffractive gratings in the input, expander and outcoupling (eyebox) areas are essential for good performing AR glasses. Advanced shapes of the gratings are used in many designs, and we here present results from masters and sub-masters having large areas with high precision, binary structures as well as both blazed and slanted gratings. Besides the waveguides used in in the displays, registration of the actual surroundings using 3D sensing is a very important feature to get the fullest out of the AR experience. We present latest developments of our compact optical solutions for 3D sensing
