The two are very different. Openwater, as per their patent filings, uses ultrasound to change the refractive index of tissue and/or phase shift and use an inverse distortion matrix to undo scattering. I've yet to see a real result on dynamically changing tissue. By contrast, this uses light to generate ultrasound waves, basically photoacoustic tomography.
