DESCRIPTION: A novel design is proposed for a portable (hand-held) ophthalmoscope with no moving parts. The instrument will incorporate the confocal contrast enhancement of the scanning laser ophthalmoscope as well as its expanded functionality as a diagnostic device. This inexpensive, light-weight ophthalmoscope is intended to serve the market presently held by the direct ophthalmoscope, and to include the market of most fundus cameras. By virtue of its portability the tandem scanning ophthalmoscope will be useful at -bedside, in pediatrics, in emergency medicine and in veterinary medicine. All of the components of this -new ophthalmoscope are readily available at the present time, so that only the optical design and implementation need to be proven in Phase I. By Phase II we intend to have a manufacturable instrument working in color (visible) or pseudo-color (infrared), in direct (confocal) or indirect (anti-confocal) mode and capable of psychophysics and fluorescence angiography, with standard resolution and ANSI compliant light levels. The display will be on TV or computer monitor, in real time. Direct comparison to the scanning laser ophthalmoscope and its variants is a part of the proposal. PROPOSED COMMERCIAL APPLICATION: The Tandem Scanning Ophthalmoscope is expected to be sold to the same market as are direct ophthalmoscopes. That includes primary care physicians, emergency medical personnel and veterinary and research users of retinal imaging devices. Lucid, Inc. will probably manufacture the instrument for sale through appropriate ophthalmological suppliers. The market could be as much as 5,000 per year world wide, and the price should eventually be as low as a few hundreds of dollars.

描述：提出了一种便携式（手持式）的新颖设计 没有活动部件的检眼镜。 该仪器将包含 扫描激光检眼镜的共焦对比度增强 以及其作为诊断设备的扩展功能。 这 价格便宜、重量轻的检眼镜旨在服务市场 目前由直接检眼镜持有，并包括市场 大多数眼底相机。 凭借其便携性，串联 扫描检眼镜将在床边、儿科、 急诊医学和兽医学。 所有组件 这种新型检眼镜目前很容易买到， 因此，仅需要验证光学设计和实现 第一阶段。到第二阶段，我们打算拥有一种可制造的仪器 直接以彩色（可见光）或伪彩色（红外）工作 （共焦）或间接（反共焦）模式并且能够进行心理物理学 和荧光血管造影，具有标准分辨率和 ANSI 合规的光照水平。 显示将在电视或电脑显示器上， 实时。 与扫描激光检眼镜直接比较 及其变体是提案的一部分。 拟议的商业应用： 串联扫描检眼镜预计将出售给同一公司 市场上的直接检眼镜也是如此。这包括初级保健 医生、紧急医疗人员以及兽医和研究人员 视网膜成像设备的用户。 Lucid, Inc. 可能会生产 该仪器通过适当的眼科供应商销售。 全球每年的市场可能多达 5,000 个，而且价格 最终应该低至几百美元。
