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.

0352969Kirkici 描述：该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。 尽管基本系统级操作原理与雷达类似，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颗粒和物体。 由于这些特性，激光雷达在污染控制、大气科学和目标识别等许多应用中比雷达技术具有主要优势。 激光雷达（LIDAR）是一种主动探测系统，利用激光作为相干光源对准目标进行探测；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 CO2 或 Nd-YAG 激光器，并已在许多发达国家用作科学和工业工具。 此外，这些激光器体积非常大，缺乏机动性，而且价格昂贵。在该项目中，PI 将研究使用低成本、轻质便携式激光系统的可行性，例如作为光源的半导体固态（二极管和/或二极管泵浦）激光器、用于检测来自光源的散射光的光电探测器和现成的光学元件来设计原型 LIDAR 系统。 将展示这种新型激光雷达系统的设计、构建和集成。 在集成阶段，他们将开发系统控制软件和成像软件来采集和分析数据。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。 两支球队经验互补。 土耳其的团队在遥感和软件开发领域颇有建树，而美国的团队在激光技术方面经验更丰富。 预计该项目将扩大参与者之间的网络和伙伴关系。研究结果将在遥感领域有非常广泛的应用，包括检测地震造成的结构损坏的能力，以及土耳其和美国持续存在的自然灾害。
