DESIGN OF DYNAMICALLY ADJUSTABLE ANAMORPHIC FRACTIONAL FOURIER TRANSFORMER

We form optical systems by using only free space portions and cylindri cal lenses, and consider these systems as anamorphic fractional Fourie r transformers, We dynamically adjust the transform order, scale facto r and field curvature of both orthogonal dimensions of anamorphic frac tional Fourier transformation by just changing the focal lengths of cy lindrical lenses used in the proposed setups. Here, we also consider t wo approaches for implementing cylindrical lenses with dynamically adj ustable focal lengths. There may also be some other methods to obtain cylindrical lenses having adjustable focal lengths which can successfu lly be used in these proposed setups.
