Abstract

The previous chapter reviewed the various optical building blocks used in typical AR and MR headsets. This chapter addresses the main challenges that must be overcome with those building blocks in order to meet the following specs simultaneously: - a large FOV and wide stereo overlap, - a large IPD coverage (large eyebox), - a large eye relief allowing prescription lens wear, - a high angular resolution close to 20/20 vision, and - a small form factor, low weight, and a CG close to the head.
