ABSTRACT
We have demonstrated image reconstruction via four-wave mixing for the case 
of a signal making a single pass through a distorting medium. Both the 
signal and the reference originate from the same source and propagate 
through the same disturbance. In the four-wave mixing process, phase 
aberrations are subtracted out. A read beam from a second source 
reconstructs the undistorted image giving a phase conjugate without a 
double pass through the disturbance. Good reconstructed image fidelity is 
demonstrated for static distortions. It is shown that this technique may 
also be used to measure the auto-correlation function of the disturbance by 
varying the mismatch between the signal and the reference in the four-wave
mixing scheme.
