Abstract : The patent discloses an apparatus and method for obtaining simultaneous measurements of the basic optical properties of seawater. It employs a pulsed beam of monochromatic light together with a variable focal length optic system to illuminate a predetermined volume of ambient fluid. A detection system measures the time decay of light energy returned from this volume and computes in real time the volume scattering function, total attenuation coefficient, the absorption coefficient and scattering coefficient of the volume.
