This PFI: AIR Technology Translation project is a proof-of-concept project to develop, demonstrate, and evaluate an innovative lidar (laser illuminated detection and ranging) remote sensing technique, called the INtrapulse PHAse Modification Induced by Scattering (INPHAMIS) technique, as a commercially viable product for detailed mapping of shallow marine environments. The INPHAMIS technique is a breakthrough technology in that it provides unprecedented, centimeter resolution to map submerged objects in shallow waters, seamlessly identifies land-to-water transitions, obtains high precision water depth measurements, and provides precise description of bottom surface topography, all from remote distances above the water. Submerged objects are the number one cause of insurance claims in watercraft and the ability to detect them in advance would take care of both a human safety concern and an economic concern. Market research indicates this type of lidar system would contribute to growing markets in the mapping of lakes, shallow glacial melt-ponds, mosquito habitat, coastal erosion, and flood basins, and provide navigation information through inlets and channels that is crucial in these ever evolving environments. The end commercial goal is to develop a mobile lidar bathymetric unit to be used for local surveys either by boat, handheld, or possibly on dirigibles or unmanned aerial systems.The INPHAMIS technique has the following unique features: 1-cm resolution in resolving objects in shallow waters, simple lidar components, noninvasive/non-contact, remote sensing technique based on a differential measurement, continuous observing over land-water transitions, and scalability to support several types of observing platforms. INPHAMIS is a disruptive technology in that it achieves high resolution subsurface mapping in water while reducing complexity and cost. Other remote sensing techniques are limited to waters deeper than a meter or more, leaving a large portion of near-shore waters unmapped. Existing lidar bathymetry systems are all quite similar in terms of intended use and capabilities and all involve large, expensive airborne systems. The INPHAMIS technique's unique features provide advantages in performance, costs, mass, power, volume, and adaptability that opens a new market in shallow-water water bathymetry by enabling the near-future development of a hand-held system for underwater mapping and subsurface target identification.This project addresses the following technology gaps as it translates from research discovery toward commercial application: 1) interactions of laser light with different surface water conditions, submerged objects, and bottom surface types; 2) performance factors and definition of system and measurement specifications; 3) trade analysis of critical lidar components. A lab demonstrator of the technique will be advanced to evaluate laser light interactions with water bodies and objects in real environmental shallow-water conditions. This will also provide data on establishing performance factors and component testing. A faculty member, graduate student, and an undergraduate student will be involved providing a unique learning environment in entrepreneurship and technology translation, with support from industry partner, ASTRA LLC, and their staff and engineers.The project engages industry partner, ASTRA LLC, which will contribute engineering experience and perform commercialization and marketing studies to assess market space, competitive environment, explore licensing opportunities and further commercialization of the technology. This strong partnership is poised to move this technology translation effort from research discovery toward commercial reality.

该PFI：AIR技术转换项目是一个概念验证项目，旨在开发、演示和评估一种创新的激光雷达（激光照明探测和测距）遥感技术，称为散射引起的脉冲内相位修正（INPHAMIS）技术，作为一种商业上可行的产品，用于浅海环境的详细测绘。 INPHAMIS技术是一项突破性的技术，它提供了前所未有的厘米分辨率来绘制浅水沃茨中的水下物体，无缝识别陆地到水域的过渡，获得高精度的水深测量，并提供对海底表面地形的精确描述，所有这些都是从水面以上的远程进行的。水下物体是船舶保险索赔的首要原因，提前检测它们的能力将兼顾人类安全和经济问题。市场研究表明，这种类型的激光雷达系统将有助于在湖泊，浅冰川融水池，蚊子栖息地，海岸侵蚀和洪水流域的测绘中不断增长的市场，并通过在这些不断变化的环境中至关重要的入口和通道提供导航信息。 最终的商业目标是开发一种移动的激光雷达测深装置，用于通过船只、手持设备或可能通过飞船或无人驾驶航空系统进行的局部勘测。分辨沃茨物体的1厘米分辨率，简单的激光雷达部件，非侵入性/非接触式，基于差分测量的遥感技术，对陆地-水过渡的连续观测，和可扩展性，以支持多种类型的观测平台。INPHAMIS是一项颠覆性的技术，它实现了高分辨率的水下测绘，同时降低了复杂性和成本。其他遥感技术仅限于水深超过一米或更深的沃茨，使近岸沃茨的很大一部分无法测绘。现有的激光雷达测深系统在预期用途和能力方面都非常相似，并且都涉及大型，昂贵的机载系统。INPHAMIS技术的独特功能在性能、成本、质量、功率、体积和适应性方面提供了优势，通过在不久的将来开发用于水下测绘和地下目标识别的手持系统，为浅水水深测量开辟了一个新市场。该项目解决了从研究发现到商业应用的以下技术差距：1）激光与不同地表水条件、水下物体和底面类型的相互作用; 2）系统和测量规范的性能因素和定义; 3）关键激光雷达组件的贸易分析。该技术的实验室演示器将被用于评估激光在真实的浅水环境条件下与水体和物体的相互作用。这还将提供关于确定性能因素和部件测试的数据。在行业合作伙伴ASTRA LLC及其员工和工程师的支持下，一名教师，研究生和一名本科生将参与提供创业和技术翻译的独特学习环境。该项目聘请行业合作伙伴ASTRA LLC，该公司将贡献工程经验并进行商业化和营销研究，以评估市场空间，竞争环境，探索许可机会并进一步将该技术商业化。这种强大的合作伙伴关系将使这项技术的转化工作从研究发现走向商业现实。
