*** 9760942 Hang This is a Small Business Innovation Research Phase I proposal. Currently, technology to help individuals with low vision consists primarily of optical or electronic magnifiers. Optical magnifiers, both microscopes and telescopes, can be hand-held, stand-mounted, or headmounted. For most such devices, magnification and focal distance are fixed. Electronic magnifiers include closed-circuit television systems, used chiefly for reading, and hardware and software to enlarge text on computer screens. Closed circuit TV's have the added capability of electronically boosting or reversing contrast. Existing displays typically use a liquid crystal display (LCD), a light emitting diodes (LED), or a miniature cathode ray tube (CRT) as an image source, which relay this image via an infinity-focus optical system to the eye. All of these display devices are bulky, heavy, and drain extensive battery power. The goal of this program is to demonstrate that a low-weight, head-mounted, low-vision display device (LDD) can be built so that the real-time, high contrast image, which is captured by a charge-coupled-device (CCD), is projected (scanned) to the healthy portion of the retina. Unlike conventional projectors, this one has no moving parts, bulky optics, or energy consuming light sources. The LDD will also be inexpensive to produce. We anticipate that this innovation will open up a new avenue in the field of head-mounted display, which has wide applications in pilot training, medicine, telemedicine, and entertainment. ***

*9760942挂起这是小型企业创新研究第一阶段的提案。目前，帮助视力低下的人的技术主要包括光学或电子放大镜。光学放大镜既可以是显微镜，也可以是望远镜，可以是手持式、立式或头戴式。对于大多数这样的设备，放大倍数和焦距都是固定的。电子放大镜包括主要用于阅读的闭路电视系统，以及在计算机屏幕上放大文本的硬件和软件。闭路电视增加了电子增强或反转对比度的能力。现有显示器通常使用液晶显示器(LCD)、发光二极管(LED)或微型阴极射线管(CRT)作为图像源，其通过无限聚焦光学系统将该图像传递到眼睛。所有这些显示设备都笨重、笨重，并会消耗大量的电池电量。该项目的目标是展示一种低重量、头戴式、低视力的显示设备(LDD)，以便将由电荷耦合设备(CCD)捕获的实时、高对比度图像投影(扫描)到视网膜的健康部分。与传统的投影仪不同，这款投影仪没有活动部件，没有笨重的光学元件，也没有耗能的光源。LDD的生产成本也很低。我们期待这一创新将为头盔显示器领域开辟一条新的道路，这一领域在飞行员培训、医学、远程医疗和娱乐领域有着广泛的应用。***
