Experiment on parallel correlated recognition of 2030 human faces based on speckle modulation.
In this paper, the experiment on parallel correlated recognition of 2030 human faces in Fe:LiNbO(3) crystal is detailedly presented, a very clear correlation spots array was achieved and the recognition accuracy is better than 95%. According to the experiment, it is proved that speckle modulation on the object beam of volume holographic correlators can well suppress the crosstalk, so that the multiplexing spacing is markedly reduced and the channel density is increased 10 times compared with the traditional holographic correlators without speckle modulation.
