An optoelectronic automatic real-time human face recognition system, which includes a feature point extractor, a normalization algorithm, an encoding module, an optical recognizer based on hit/ miss transform and an incoherent correlator, and a postprocessing module is presented in this paper.

Based on a hybrid opto electrical image processing system with an incoherent correlator, the image matching algorithm using optical Walsh transformation is realized successfully.

In this paper, a multi channel optical target recognition approach based on morphological hit or miss transformation and incoherent correlator is presented.

In this paper, we propose a novel digital matrix vector multiplication and the incoherent optical correlator to compute discrete wavelet transforms.

Effect of incoherent beam on photorefractive two-wave mixing in Ce∶KNSBN crystal;

From BaTiO_3:Ce self-pumped phase conjugator, it is theoretically analysised and experimentally demonstrated that non-negative effect of incoherent beam on the four waive mixing region in photorefractive phase conjugator.

This result is experimentally achieved by using incoherent beam illumination along the c axis  direction of the crystal when a He Ne laser generates steady phase conjugate signal.
