| Abstract: | The fractional fourier transform is a new concept which is put forwarded recently and has much important application in optical information processing field.In this paper, a method for implementation of the multiple spectrum fractional fourier transform using a multi focus hololens is proposed. The multi focus hololens is made with holographic method and the conditions for using it as a transform element is analyzed in theory. In laboratory,the multiple spectrum fractional fourier transform is realized. The experimental result shows this transform method is simple and feasible, and it can be used in multi channel optical information processing systems and multi object recognition systems. |
