Experimental demonstration of a continuously variant fractional fourier transformer.
We demonstrate that an off-axis illuminated hemispherical-rod microlens acts as a fractional Fourier transformer with a continuously varying degree of fractionality. A complete theoretical treatment of the device as well as experimental results are presented.
