Abstract

We present the results of an adaptive optics system used to observe an object through the water surface. To be compact the system was composed of two refractive wavefront modulators mounted in stack configuration. One of the devices is a novel concept of tip/tilt refractive wavefront corrector. The second one is a deformable lens for correcting aberrations up to the 4th order. The two devices were driven using a Shack Hartmann wavefront sensor and a far field camera. The system was designed to be compact (about 15cm x 30cm) and was mounted in a sealed container placed below the surface in a water tank at NRL lab. The results show that the system was able to correct the wavefront with moderate waves amplitude. The simultaneous correction of tilt and high order aberrations demonstrated to be more efficient for the higher waves level.
