  • System and method for ratiometric non-linear coherent imaging
    Patent number: 7869051
    Abstract: The present invention includes a system and method for coherent imaging. The system of the present invention includes a light source adapted to provide coherent light to illuminate a sample resulting in optically mixed coherent signals and a detector adapted to receive the optically mixed coherent signals and produce an output signal in response thereto. The optically mixed coherent signals will be a set of sum and difference frequency combinations of the frequencies in the coherent light. A processor is connected to the detector and adapted to ratio a selected two of the optically mixed coherent signals in response to the output signal received by the detector and to generate an image in response to the ratioed optically mixed coherent signals, which can be displayed for a user.
