Abstract:
1. A method for optimizing linear optoacoustic communication from an in-air platform to an undersea receiver, said method comprising the steps of: utilizing at least one laser beam containing a communications signal; firing a first collection of lasers with the at least one laser beam from the in-air platform to a water medium with the at least one laser beam capable of being optically absorbed within the water medium with an identifiable optical absorption coefficient; identifying waveshape data and a sound pressure level with the undersea receiver; determining a communication in-water range of the at least one laser beam based upon the identified sound pressure level and identified waveshape data; increasing the power of the at least one laser based upon the determined communication in-water range; and varying a signal frequency relative to said increasing power step of the at least one laser beam based upon the identification of the optical absorption coefficient and the determined communication in-water range in order to determine a suitable signal frequency and power level coincident to a suitable in-water range required for optimized linear optoacoustic communication.
