| Summary: | 碩士 === 國立交通大學 === 光電工程研究所 === 107 === There is a huge variety of AR glasses in the market recently. However, each type of AR glasses can only fit in some specific niche application. The reason why that the diversity of AR glasses exists is that different AR application scenarios request different form factor, such as ID design and content display. Technology nowadays just cannot meet all the different situation needs with a single model.
In order to solve this problem, an off-axis optical architecture with single microdisplay is proposed in this study. The concept of this experiment is to add AR display function to currently exists glasses without changing its form factor and ID design with minimizing extra weight loading. Due to the very little space between face and the glasses, inserting optical light path can be hard. We make the major extra weight be added over nose and ear, where direct support is underneath.
The sport glasses chosen for the prototype is a ski goggle provided by Argus Vision. A free-form surface is chosen for optical component use. To reduce the eye relief and increase the field of view through the configuration of the optical architecture, in which only single display panel is used for both views. Although the resolution has to be diminished into half for each view, it still sufficient for sporting application scenarios, such as heart beating rate, blood sugar, PM2.5, and direction pointing arrow.
Finally, we successfully develop a prototype of glasses through ultra-precision machining.
