DEVICE FOR REMOTE OIL DETECTION

摘要

This relates to the field of real-time detection of chemical contamination of water in harsh environmental conditions by using laser remote sensing apparatus for detection of oil or oil products. In-time detection and localization of oil pollution in seawater are the measures to minimize potential damages to the marine and coastal environment. A technical solution for remote detection and classification of chemical pollution in water, to optimize operational parameters, weight, size and power consumption of such device, to make possible continuous unattended operation of such device on board of a moving or stationary platform and to provide data processing and reporting the results through communication channels is described.
