3-D image correlator using optically reconstructed integral plane images

摘要

In this paper, we propose an optical method for 3-D image correlator using reconstructed integral plane images. In the proposed correlator based on integral imaging, elemental images of the reference and signal 3-D objects are recorded by lenslet arrays and then reference and signal integral plane images are optically reconstructed on the output plane by displaying these elemental images into a display panel. Through cross-correlations between the reconstructed reference and the single plane images, 3-D object recognition is performed. The proposed method can provide all-optical structure for real-time 3-D object recognition system. To show the usefulness of the proposed method, optical experiments are carried out and the results are presented as well.
