We report a technique to produce three-dimensional maps of transparent objects using the Kerr coefficient as a contrast agent. The method is based on the spatial modifications of a probe pattern focused into the medium. (C) 2010 Optical Society of America ...
We report experimental image reverse propagation in focusing Kerr media. These results are compared with a linear Zernike filter operation. A method for the measurement of the nonlinear coefficient is derived from these results. (C) 2010 Optical Society of ...

Lenses allow the formation of clear images in homogeneous linear media. Holography is an alternative imaging method, but its use is limited to cases in which it provides an advantage, such as three-dimensional imaging. In nonlinear media, lenses no longer ...
We demonstrate a simple method to detect small phase steps using propagation in Kerr media. In experiments, nonlinear diffraction in acetone produced high contrast signals for a pi/80 phase mask. (C) 2010 Optical Society of America ...

We demonstrate experimentally a scanning confocal microscopy technique based on digital holography. The method relies on digital holographic recording of the scanned spot. The data collected in this way contains all the necessary information to digitally p ...
