U.S.-Turkey Cooperative Research: A Novel LIDAR System Development and Studies for Remote Sensing

描述：本项目支持由阿拉巴马州奥本大学电气与计算机工程系Hulya Kirkici博士和土耳其伊斯坦布尔技术大学建筑与大地测量系Cankut Ormeci博士领导的团队之间的合作项目。他们计划研究开发更小、更轻、成本更低的激光雷达（光探测和测距）系统。激光雷达已应用于空间应用、地球科学、目标识别和测距等多个领域。虽然基本的系统级操作原理与雷达相似，但激光雷达的工作频率要高得多，因此可以产生更高的空间分辨率，并且可以以更高的精度跟踪快速移动的粒子和物体。由于这些特点，激光雷达在污染控制、大气科学和目标识别等许多应用中具有比雷达技术更大的优势。激光雷达是一种主动探测系统，它使用激光作为相干光源直接对准目标进行探测；然而，在某些应用中存在光谱和空间分辨率问题。目前的激光雷达系统基于非常昂贵的技术，使用二氧化碳或Nd-YAG激光器，并已在许多发达国家作为科学和工业工具使用。此外，这些激光器非常大，缺乏机动性，而且价格昂贵。在这个项目中，pi将研究使用低成本和低重量的便携式激光系统的可行性，例如半导体固态（二极管和/或二极管泵浦）激光器作为光源，光电探测器检测来自光源的散射光，以及现成的光学元件来设计原型激光雷达系统。将演示这种新型激光雷达系统的设计、构造和集成。在集成阶段，他们将开发系统控制软件和成像软件，以获取和分析数据。范围：拟议的研究将促进美国和土耳其研究人员之间的关系。这两个团队经验互补。土耳其集团在遥感和软件开发领域建立良好，而美国集团在激光技术方面更有经验。预计该项目将扩大参与者之间的网络和伙伴关系。这些结果将在遥感方面有非常广泛的应用，包括探测地震造成的结构破坏的能力，地震是土耳其和美国经常发生的自然灾害。

0352969KirkiciDescription: This project supports a collaborative project between a team headed by Dr. Hulya Kirkici, Department of Electrical and Computer Engineering, Auburn University, Auburn, Alabama and Dr. Cankut Ormeci, Department of Construction and Geodesy at Istanbul Technical University, Istanbul, Turkey. They plan to study the development of smaller, lighter and less costly LIDARs (Light Detecting and Ranging) systems. LIDAR has been used in several areas such as space applications, earth science, target recognition and ranging. Although the basic system level operating principles are similar to radar, LIDARs operate at much higher frequencies and can therefore produce much higher spatial resolution, and can track fast moving particles and objects with higher accuracy. Because of these characteristics, LIDARs have a major advantage over radar technology in many applications such as pollution control, atmospheric science, and target recognition. LIDAR is an active detection system that uses lasers as the coherent light source directed at the target for detection; however, there are spectrometric and spatial resolution issues in some applications. Current LIDAR systems are based on very expensive technology that uses CO2 or Nd-YAG lasers, and have been used in many developed countries as a scientific and industrial tool. Furthermore, these lasers are very large, lacking mobility, and are expensive. In this project the PIs will study the feasibility of using a low cost and low weight portable laser system, such as semiconductor solid state (diode and/or diode pumped) laser as the light source, a photodetector to detect the scattered light from the source, and off-the-shelf optical components to design a prototype LIDAR system. Design, construction, and integration of this novel LIDAR system will be demonstrated. During the integration stage, they will develop system control software and imaging software to acquire and analyze data. Scope: The proposed research will foster a relationship between researchers in the US and in Turkey. The two teams have complementary experiences. The group in Turkey is well established in the field of remote sensing and the development of soft ware whereas the US group is more experienced with laser technology. It is anticipated that this project will broaden the networks and partnerships among the participants. The results will have very broad applications in remote sensing, including the ability to detect structural damage due to earthquakes, a constant natural hazard in Turkey and in the United States.
