Abstract:In this paper, a technology of implementation of the multichannel fractional Fourier transform ( FRT) is pro-posed using holographic lens array. The princip le ofmaking holographic lens array is analyzed. The multichannel FRT with different fractional order is implemented for several objects. We have compared the experimental results of FRT using holographic lens array with that using op tical lens. As a result, both fractional spectra are consistent. The mu-tichannel FRT can be app lied in the multichannel op tical information p rocessing and the mutitarget recognition.
