It has been demonstrated that interferometers using nonlinear optics are suitable for the task of examining underwater surface deformations that are much larger than optical wavelengths. The demonstration has been limited to 1.06-micron devices whose sensitivity is of the order of 100 micron. The precise sensitivity is somewhat adjustable by examining the object in transmission rather than reflection. The device has been operated under simulated field conditions, and has proved to be insensitive to high levels of vibration. The attempt to make a more sensitive device operating at 0.69 micron has not been successful. Author
