Imaging analysis by means of fractional fourier transform
Starting from the diffraction imaging process, we have discussed the relationship between optical imaging system and fractional Fourier transform, and proposed a specific system which can form an inverse ampli...

An optical fractional fourier transform system
An alternative way to perform fractional Fourier transform is proposed. The system is illuminated by a divergent beam. It has one more degree of freedom in arrangement than the previous system. Mathematically,...
