ABSTRACT:
Using an array of optical sensors affixed to measure interactions on a surface of an object, in combination with a specially configured personal computer, dynamic mapping of interaction is provided. One application maps washover of an object towed in a large body of water. Data are collected on optical characteristics of the interaction such as reflectivity at a boundary. For example, in one embodiment the reflectivity at an optical fiber/seawater boundary is compared to that of an optical fiber/air boundary and dynamic measurements made using an optical time domain reflectometer (OTDR). These data are then processed using specialized software to yield representation of the dynamics (spatial and temporal) of selected washover events on a surface of interest. The system specifically provides a real-time representation of washover, including two and three-dimensional visualization of washover, as well as recording selected data for future use. Methods of employment of the system are also provided.
