3-D Laser Imaging and Tracking Electro-Optical System

海港分部海洋学研究所将开发和测试用于生物海洋学的三维激光成像和跟踪光电系统（3-D LITES）。该激光扫描系统将提供近乎实时的精确3d数据，同时结合高分辨率（1.25毫米）、大视场（0.5米）和长工作距离（1米）。该系统将在实验室和现场使用。3-D LITES是为海军开发的用于水下表面高分辨率测绘的系统的改进版。该图像与分辨率为200至800行的视频图像非常相似，但每帧都是一个3-D数据文件，其中组成图像的“像素”除了X、Y坐标外还具有“Z”分量，从而在传感器的视场内提供真正的三维成像。提出的工作是将这种设计用于绘制海洋生物的实时运动和微尺度分布模式。其主要应用是测量海洋中活动生物的空间分布和游动模式。这代表了生物海洋学中最大的挑战之一，并且通过回答诸如共生物种如何在空间中相对于彼此以及相对于环境中的物理变量分布等基本生态问题，掌握了理解浮游动物行为生态学的关键。Dr. Edith Widder Harbor Branch Oceanographic institute . 5600 U.S. 1 North Ft.

9318399 Widder The Harbor Branch Oceanographic Institution will develop and test a three dimensional, laser imaging and tracking electro-optical system (3-D LITES) for applications in biological oceanography. This laser-scanning system will provide precise 3-D data in near real time while combining high resolution (1.25 mm) with a large field of view (0.5 m) and a long working distance (1 m). The system will be for use both in the laboratory and in situ. 3-D LITES is a modification of a system developed for the the Navy for high resolution mapping of surfaces underwater. The image closely resembles a video image with 200 to 800 lines of resolution, but each frame is a 3-D data file where the "pixels" comprising the image have a "Z" component in addition to an X,Y coordinate, thus providing true three-dimensional imaging within the sensor's field of view. The work proposed is to adapt this design for mapping real time movements and microscale distribution patterns of marine organisms. The principal application is the measurement of spatial distributions and swimming patterns of motile organisms in the open ocean. This represents one of the greatest challenges in biological oceanography and holds the key to understanding zooplankton behavioral ecology by answering such basic ecological questions as how co-occurring species distribute themselves in space relative to each other and relative to the physical variables in their environment.
