  • Non-invasive visualization and quantification of natural pigments
    Patent number: 10653355
    Abstract: A system for visualizing melanin present in tissue can include an imaging system to record a signal based on a presence of melanin in tissue and a display device to display an image based on the signal. A first laser source can emit a Stokes pulse train and a second laser source can emit a pump pulse train. Both the first laser source and the second laser source comprise a tunable center wavelength or frequency. An energy difference between a frequency of the Stokes pulse train and a frequency of the pump pulse train is from 1750 cm?1 to 2250 cm?1. The Stokes and the pump pulse train overlap in space and time. A scanning mechanism focuses the combined Stokes pulse train and pump pulse train within the tissue and scans across the tissue. A detector detects the signal based on a presence of melanin within the tissue.
