Optimization Studies for Applications of a Scanned Light Display

虚拟视网膜显示器(VRD)是华盛顿州西雅图人机接口技术实验室开发的一种新型显示设备。这种设备直接扫描光线进入眼睛，在视网膜上产生图像。预计VRD将成为一种无处不在的显示设备，因为它将被微型化，可以佩戴在眼镜框上。VRD是明亮的，但安全的，使用激光作为高度色彩饱和的光源。这项提议的研究将是对扫描图像的光感知的基本原理的研究。这些研究将使我们能够优化扫描特性，以获得最佳的颜色、分辨率和对比度。我们打算了解扫描光的视网膜处理元件的时间和空间整合的特征，以及这种整合是如何影响图像感知的。然后我们将能够产生具有出色的色彩匹配和图像清晰度的图像。通过在这项研究中优化VRD，我们将允许在图像质量至关重要的地方使用它，例如在远程手术或外科培训中。此外，VRD具有明亮、高质量的图像，这将使其非常适合用于增强视觉应用，其中图像叠加在真实世界上。

The Virtual Retinal Display (VRD) is a new form of display device developed at the Human Interface Technology Laboratory in Seattle, Washington. This device scans light directly into the eye to create images at the retina. It is anticipated that the VRD will become a ubiquitous display device as it will be miniaturized to wear on a spectacles frame. The VRD is bright, yet safe and uses lasers as highly color saturated sources of light. The research from this proposal will be studies on the fundamentals of light perception of scanned images. These studies will allow us to optimize the scan characteristics for best color, resolution and contrast. We intend to understand the features of temporal and spatial integration by the retinal processing elements of the scanned light and how that integration affects the image perception. We will then be able to produce images with excellent color matching and image sharpness. By optimizing the VRD in this research we will allow its use where image quality is essential, such as in remote surgery, or surgical training. Further, bright, high quality images with the VRD will make it excellent for use in augmented vision applications, where images are superimposed on the real world.
