军事潜水行动通常在地球上最恶劣的环境之一进行，通常能见度为零。历史上，无法清楚地看到直接操作环境一直是载人潜水作业的严重限制——无论任务是船舶管理、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，持续要求对水柱进行载人干预。为了确保整个潜水作业领域的技术优势，我们必须识别、利用和开发技术来推进最先进的潜水设备。 This can only be achieved by investing in, and supporting, focused research and development with specific goals to further diving capabilities.在海军研究办公室 (ONR) 和海军海洋系统司令部 (NAVSEA) 赞助的一个项目下，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款原型透视平视显示系统——潜水员增强视觉显示器 (DAVD)。 DAVD 系统使用波导光学显示模块，将微型显示器中的图像耦合到波导光学器件中，通过一系列内反射转换图像，最终射向潜水员的眼睛，在潜水员前方特定距离处提供放大的透明虚拟图像。虚拟图像可以是关键信息和传感器数据，包括声纳图像、船舶管理和水下施工示意图、增强型导航显示、增强现实和文本消息。 NSWC PCD 是美国海军领先的潜水员视觉显示系统研究、开发、测试、评估和技术转化实验室； with unique facilities for rapid prototyping and manufacturing, human systems integration and extreme environment testing.与 NSWC PCD 一样，海军实验潜水单位 (NEDU) 以及海军潜水和打捞训练中心 (NDSTC) 均位于巴拿马城海军支援活动中心 (NSA PC)。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 原型机的开发、潜水员评估结果以及加速发展这种改变游戏规则的能力的建议。
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.
