Abstract: The invention is directed to a remote 3-D imaging system which uses a novel illumination source to establish the relationship of the image features to the system, which is displayed by virtue of calculations. In addition to static surfaces, moving surfaces may be studied and corrections due to turbidity and platform position are also easily compensated for. The instant system may also contain a plurality of sensing systems based on light, including traditional reflective or elastic scattering and novel fluorescent or non-elastic scattering still and video imaging systems, including time-gated systems.

Abstract: A communication method and a data collection and transmission system are provided having at least one remotely located monitoring station. A central computer is arranged for bidirectional communication with each of the monitoring stations. Each of the monitoring stations includes a storage and forward unit for communicating with the central computer and at least one sensor unit for monitoring a predetermined geographically proximate variable and for processing and storing predetermined operational data. The storage and forward unit includes a real time clock that is arranged to accurately maintain a real time indicative signal. A local area network connects the storage and forward unit and each of the sensor units. A coded message having a predetermined sequential data format is used for bidirectional communications between the storage and forward unit and the sensor units. A real-time coded message is provided by the storage and forward unit to the sensor units.
