Paper Abstract

In this paper, a new real-time optical image switching system based on the binary phase extraction joint transform correlator (BPEJTC) is suggested. The phase filter which has the arbitrary position mapping function between input and output plane is constructed by using the modified joint transform power spectrum (JTPS) of the BPEJTC. Then, the input image is multiplied by this phase filter in the spatial frequency plane and through further Fourier transform the input image is switched to the new positions in the output plane where the correlation peaks are occurred. The practical optical switching system is opto-digitally constructed and through some experiments the possibility of real-time implementation of the image switching system is suggested.
