项目摘要

The broader impact/commercial potential of this Partnerships for Innovation-Technology Translation (PFI-TT) project is a new modality for light detection and ranging (LIDAR), an optical technique that generates high-resolution images of an object. LIDAR is commonly used in applications such as mapping, agriculture, energy and environmental studies, and more recently, for autonomous navigation and collision avoidance for self-driving cars, drones, and satellites. These applications are all crucial to societal function today. For example, surveying the snow pack can be important for hydroelectric power and drinking water estimates. Other important applications include mapping coastlines, as well as determining the health of agricultural crops and trees to predict yields as well as fire risks. However, the mechanical-based LIDAR scanners currently used have a limited lifetime, are large, and power hungry. This can cause significant constraints; for example, a drone can only carry a very limited and small system, or battery life will be impacted. Nonmechanical scanning methods can offer a solution. The research will demonstrate an innovative technique for nonmechanical scanning applied to LIDAR systems.The proposed project focuses on an incoherent light detection and ranging (LIDAR) system, using nonmechanical beam steering with adaptive optical elements. The system is compact, versatile, and ultra-low power. It will enable a new generation of systems that are able to adapt with agility to changing conditions and targets. Unlike conventional LIDAR systems which often use beam steering based on prisms or gimbals that rely on mechanically moving parts, which can be heavy, power hungry, and have a limited lifetime, the proposed LIDAR design has operational lifetime orders of magnitude longer due to nonmechanical components. The proposed work will enable new LIDAR technology with enhanced capabilities (ability to adapt to changing conditions) and steer the technology in a direction for eventual commercialization.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该创新技术翻译合作伙伴关系 (PFI-TT) 项目的更广泛影响/商业潜力是一种新的光检测和测距 (LIDAR) 模式，这是一种生成物体高分辨率图像的光学技术。激光雷达通常用于测绘、农业、能源和环境研究等应用，最近还用于自动驾驶汽车、无人机和卫星的自主导航和防撞。这些应用对于当今的社会功能都至关重要。例如，测量积雪对于水力发电和饮用水估算非常重要。其他重要应用包括绘制海岸线地图，以及确定农作物和树木的健康状况以预测产量和火灾风险。然而，目前使用的基于机械的激光雷达扫描仪的使用寿命有限，而且体积大且耗电。这可能会造成严重的限制；例如，无人机只能携带非常有限的小型系统，否则电池寿命将受到影响。非机械扫描方法可以提供解决方案。该研究将展示应用于 LIDAR 系统的非机械扫描创新技术。拟议项目的重点是非相干光检测和测距 (LIDAR) 系统，使用带有自适应光学元件的非机械光束控制。该系统结构紧凑、多功能且超低功耗。它将使得新一代系统能够灵活地适应不断变化的条件和目标。传统的 LIDAR 系统通常使用基于棱镜或万向节的光束转向，这些部件依赖于机械移动部件，这些部件可能很重、耗电且使用寿命有限，而所提出的 LIDAR 设计由于采用非机械部件，因此使用寿命延长了几个数量级。拟议的工作将使新的激光雷达技术具有增强的能力（适应不断变化的条件的能力），并引导该技术走向最终商业化的方向。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优势进行评估，被认为值得支持以及更广泛的影响审查标准。
