Abstract
A new method is proposed to correct the nonlinear distortion of a practical hardware optical implementation system. The on-line optical-computer feedback technique and off-line digital iterative algorithm are used to correct the correlation matrix of a SDF and the input-output vector respectively. As a result, a optimum SDF with very good correlation S/N, minimum peak variance, is obtained. Experiments demonstrate that this method is very effective for correcting the nonlinear distortion of a real-world nonideal optical and optoelectric system, so it could be applied to 3D distortion invariant real-time optical correlation filtering and optical pattern recognition.
