Abstract: An apparatus for detecting sea mines is disclosed. The apparatus includes a pulsed laser, a collection optics, a long-pass beam splitter, a short-pass beam splitter, a Laser Imaging, Detection and Ranging (LIDAR) channel imager, a Raman channel imager and a florescence channel imager. After the pulsed laser has sent a laser pulse to an ocean surface, the collection optics collects Rayleigh, Raman and florescence scattering return signals reflected from the ocean surface as a result of the laser pulse laser striking the ocean surface and any objects therein. The long-band beam splitter directs the Rayleigh scattering return signals to the LIDAR channel imager. The short-band beam splitter directs the Raman return signals to the Raman channel imager, and directs the florescence return signals to the florescence channel imager.
