| Abstract: | Using a combination of linear polarization filters, a new method to generate the optical Hilbert transform (OHT) is described. Linear polarizers, acting as knife-edge filters in the spatial frequency plane and together with an image plane analyzer, can produce at the output, the input signal, its analytical function and its OHT. Both one and two dimensional, also angularly anisotropic and isotropic, OHTs are discussed. With a white light source, this method also produces a white light HT (WHT). |
