dc.description.abstract | 本文提出四種用於頭戴式顯示裝置的環境光調光模組,藉由電控轉動100μm等級的微結構控制環境光進光量,其微結構單元為雙色小球,一半為吸光材料,另一半為透光材料。調光模組分成穿透態及遮蔽態,切換後不需消耗功率即可維持任一狀態。依據模擬結果,所設計之遮光元件之穿透態穿透率皆可大於50%,遮蔽態穿透率皆可小於10%,對比度可達到10。另外,我們將調光模組模型進行近眼成像的模擬,探討MTF與微結構的繞射效應,針對不同空間頻率對比度的影響歸納出MTF表現較好的型態。 | zh_TW |
dc.description.abstract | In this thesis, we have proposed four kinds of transmission-adjustable-dimming module for head-mounted see-through displays. The transmittance of ambient light is controlled by electronical-rotating microstructures with size around 100μm. The unit of microstructure is a bichromal bead which is with half opaque and half transparent. There are transparent state and dark state in the dimming modules. The dimming modules do not require power to maintain the state. According to the simulation results, transmittance of the transparent-state can be as high as 50%, the transmittance of the dark-state can be as low as 10%, and the contrast ratio reaches around 10. Finally, we make simulation to evaluate the performance of dimming modules in near-eye imaging system. Through MTF analysis, we can find the influence of the diffraction effect caused by microstructure, and then we can optimize the design. | en_US |
