Optical design and analysis of a head-mounted display with a high-resolution insert
In a previous paper by the authors, a High-Resolution Insert Head-Mounted Display (HRI- HMD) that uses only fixed electronic devices was proposed and designed. The design concept is innovative and it is the first and only known such design to implement a high-resolution insert for HMDs. The high resolution insert system consists of three stages: an objective to collimate the image of the display, a duplicator to produce insert images, and an eyepiece to view the insert and background images. In this paper, a detailed description of the HRI-HMD is given, which includes detailed analysis of the performance and a discussion of physical constraints. Analysis is conducted for each stage as well as for the entire system. The potential benefits of individually optimizing each channel of the duplicator and balancing aberrations from different stages are discussed. The benefits of employing binary optics at the duplicator are also discussed. The geometry of a folded model is described as well. From this analysis, the achievable performance of the HRI-HMD can be estimated against its size and cost.
