摘要

军事潜水行动通常在地球上最不适宜居住的环境之一进行,通常以零能见度为特征。从历史上看,无法清楚地看到直接的操作环境一直是载人潜水操作的严重限制-无论是船舶管理,水下施工,打捞还是科学研究。美国海军潜水是国家国防战略的一个组成部分,持续要求在水柱中进行载人干预。为了确保在整个潜水作业范围内的技术优势,我们必须识别、开发和开发技术,以推进最先进的潜水设备。这只能通过投资和支持有针对性的研究和开发来实现,这些研究和开发具有进一步提高潜水能力的具体目标。根据海军研究办公室(ONR)和海军海上系统司令部(NAVSEA)赞助的一项项目,海军水面作战中心-巴拿马城分部(NSWC PCD)为美国海军潜水头盔开发了一种原型透明平视显示系统——潜水员增强视觉显示器(DAVD)。DAVD系统使用波导光学显示模块,将来自微型显示器的图像耦合到波导光学中,通过一系列内部反射转换图像,最终射向潜水员的眼睛,在潜水员面前的特定距离处提供放大的、透明的虚拟图像。虚拟图像可以是关键信息和传感器数据,包括声纳图像、船舶管理和水下建筑原理图、增强导航显示、增强现实和文本信息。NSWC PCD是美国海军研究、开发、测试、评估和潜水员视觉显示系统技术转换的领先实验室;拥有独特的快速原型和制造,人类系统集成和极端环境测试设施。与NSWC PCD一起,海军实验潜水单位(NEDU)和海军潜水和打捞训练中心(NDSTC)位于海军支持活动巴拿马城(NSA PC)的共用租户命令。本文简要介绍了潜水员平视显示系统的发展背景,波导光学显示技术,DAVD原型的发展,潜水员评估的结果,以及加速发展这种改变游戏规则的能力的建议。

Divers augmented vision display (DAVD) emerging technology development
Military diving operations are routinely conducted in what can be one of the most inhospitable environments on the planet, frequently characterized by zero visibility. The inability to clearly see the immediate operational environment has historically been a serious limitation to manned diving operations — whether the mission is ship husbandry, underwater construction, salvage, or scientific research. U.S. Navy diving is an integral part of the nation's defense strategy with a continuing requirement to conduct manned intervention in the water column. To ensure technical superiority across the entire spectrum of diving operations we must identify, exploit, and develop technology to advance the state-of-the-art in diving equipment. This can only be achieved by investing in, and supporting, focused research and development with specific goals to further diving capabilities. Under a project sponsored by the Office of Naval Research (ONR) and Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center-Panama City Division (NSWC PCD) has developed a prototype see-through head-up display system for a U. S. Navy diving helmet — the Divers Augmented Vision Display (DAVD). The DAVD system uses waveguide optical display modules that couple images from a micro display into a waveguide optic, translate the images through a series of internal reflections, finally exiting toward the diver's eye providing a magnified, see-through virtual image at a specific distance in front of the diver. The virtual images can be critical information and sensor data including sonar images, ship husbandry and underwater construction schematics, enhanced navigation displays, augmented reality, and text messages. NSWC PCD is the U.S. Navy's leading laboratory for research, development, testing, evaluation, and technology transition of diver visual display systems; with unique facilities for rapid prototyping and manufacturing, human systems integration and extreme environment testing. Along with NSWC PCD, the Navy Experimental Diving Unit (NEDU), and Naval Diving and Salvage Training Center (NDSTC) are co-located tenant commands at the Naval Support Activity Panama City (NSA PC). This paper provides a brief background on the development of diver head-up display systems, waveguide optical display technology, development of the DAVD prototype, results of diver evaluations, and recommendations for accelerated development of this game changing capability.
