Standoff real-time detection of floating and submerged objects in ocean water.

ABSTRACT: Detecting and identifying floating or submerged objects in the ocean is very challenging with the current state of the art maritime-LIDAR technology. A LIDAR sensor has limitations in detecting objects that are near the surface of water due to strong glint produced by the reflection of the laser from the surface of water. In addition, whitecaps, foam, and air bubbles give strong scattering signals which make it difficult for a LIDAR sensor to detect and identify an object which is floating or is just below the ocean surface. We have developed a fluorescence sensor for standoff detection of objects that are either floating or submerged in shallow ocean waters. The fluorescence sensor is an active sensor that utilizes a nano-second Nd:YAG laser simultaneously emitting 355 and 532 nm laser pu
