这个小型企业创新研究二期项目开发、构建和部署了一个基于光纤传感器的沿海海洋过程传感器（COPS）阵列。COPS使用数字全息技术和小波变换光学相关技术来记录和分析海洋微粒。机会识别：颗粒的详细特征是了解海底环境的核心。cop通过一系列与中央数据处理器相连的全息传感器来测量各种分散地点的微粒。重要的应用包括颗粒沉降速度的测量和水生系统中生物地球化学过程的分析。研究目的：建立和验证一组cop传感器。每个COPS传感器记录一个三维的微粒场，用于小波分析和分类。研究描述：COPS传感器将通过一系列海上试验进行建造、测试和改进。几个传感器将协同部署，以验证一个完整的COPS监测阵列的能力。预期结果：COPS设计将强调自主操作、低功耗要求和抗生物污染。cop阵列应该在没有操作人员注意的情况下原位运行数周。商业应用包括海洋聚集体粒子动力学的研究，涉及生物、化学和物理过程。其他应用包括海岸监测、环境调查、水产养殖、工程浊度、工业设施监测和水下激光雷达。＊＊＊

*** 9801493 Owen This Small Business Innovation Research Phase II project develops, constructs, and deploys a Coastal Ocean Processes Sensor (COPS) array of fiber-optics based sensors. COPS uses digital holography and wavelet-transform optical correlation to record and analyze ocean particulates. Identification of the opportunity: Detailed characterization of particulates is central to understanding the subsea environment. COPS measures particulates at a variety of scattered sites with a collection of holographic sensors linked to a central data processor. Important applications include the measurement of particle settling velocities and the analysis of bio-geochemical processes in aquatic systems. Research objective: To build and verify a collection of COPS sensors. Each COPS sensor records a 3-D field of particulates for wavelet analysis and classification. Research description: COPS sensors will be constructed, tested, and refined through a series of sea trials. Several sensors will be deployed in concert to verify the capabilities of a full COPS monitoring array. Anticipated results: COPS design will emphasize autonomous operation, low-power requirements, and biofouling resistance. A COPS array should operate in-situ for several weeks without operator attention. Commercial applications include studies of marine aggregate particle dynamics involving biological, chemical, and physical processes. Other applications include coastal monitoring, environmental surveying, aquiculture, engineering turbidity, industrial facility monitoring, and underwater lidar. ***
