Cascading the multiple stages of optical fractional Fourier transforms under different variable scales.
A simple but necessary condition for cascading the multiple stages of an optical fractional Fourier transform with different variable scales is presented. That condition permits more flexibility in the design of optical information-processing systems that use optical fractional Fourier transforms. We have expanded the optical applications of fractional Fourier transforms with adjustable variable scales.
