  • Method and apparatus for measuring the optical scattering co-efficient of the ocean using large and small fields of view
    Patent number: 4754151
    Abstract: The method of measuring the optical scattering co-efficient of the ocean by means of a laser beam (15) from a platform (16) above the ocean surface (3) in which an ocean penetrating beam (15) is swept across the direct path of travel to the surface of the ocean (3) and through it to the ocean bottom (4) to be back-reflected to the ocean surface (3) and to a receiver on the platform (16) characterized by changing the field of view to alternately use a small and a large field of view and calculating from the larger field of view an estimate of the absorption co-efficient and from the smaller field of view an estimate of beam attenuation co-efficient.
