在这项研究中，我们提出了一种新的头戴式显示器（HMD）设计，用于近眼光场显示，实现了增强现实的透明和宽视场。在过去的几年里，许多光学元件如半反射镜、分束器和波导被用于光学透明显示。我们使用透射镜装置（TMD）代替传统的光学元件。TMD由许多微镜组成，通常用于空中真实成像系统。为了将以前的近眼显示扩展到透明显示，我们引入了一种新的TMD板的显示方法。我们通过微透镜阵列创建点光源来实现宽视场和舒适的观看。我们的配置非常简单，包括一个LCD作为图像源，一个微透镜阵列提供光场，以及一个TMD板在眼睛前面提供航空图像。我们构建了一个原型透明显示器，包括一个预制的头戴式显示器。我们使用模拟和实验验证了我们的原型设计，并进一步讨论了构建新型近眼透明显示器的挑战。
In this study, we propose a novel head-mounted display (HMD) design for near-eye light field display which achieves a see-through and wide field of view for augmented reality. In the past years, many optical elements such as half-mirror, beamsplitter, and waveguide were employed for an optical see-through display. We use a transmissive mirror device (TMD) instead of conventional optical elements. A TMD consists of numerous micro-mirrors and is usually used for real imaging system in the mid-air. We introduce a new method for the TMD plate in order to extend the previous near-eye display to the see-through display. We achieve a wide field of view and comfortable viewing by creating a point light source with a micro-lens array. Our configuration is very simple and consists of a LCD for the image source, a micro-lens array to provide the light field, and a TMD plate to provide the aerial image in front of the eye. We construct a prototype see-through display including a fabricated HMD. We verify the design of our prototype using simulations and experiments, and further discuss the challenges in building a novel near-eye, see-through display.
