Optimal multicriteria approach to the iterative fourier transform algorithm.
We propose a unified approach to the multicriteria design of diffractive optics. A multicriteria version of the direct binary search that allows the user to adjust the compromise between the diffraction efficiency and the signal-to-noise ratio already exists. This technique has proved to be extremely powerful but also very time consuming. We extend this multicriteria approach to the iterative F...
متن کاملOptical implementation of iterative fractional Fourier transform algorithm.
An optical implementation of iterative fractional Fourier transform algorithm is proposed and demonstrated. In the proposed implementation, the phase-shifting digital holography technique and the phase-type spatial light modulator are adopted for the measurement and the modulation of complex optical fields, respectively. With the devised iterative fractional Fourier transform system, we demonst...
متن کاملFractional-Fourier-transform calculation through the fast-Fourier-transform algorithm.
A method for the calculation of the fractional Fourier transform (FRT) by means of the fast Fourier transform (FFT) algorithm is presented. The process involves mainly two FFT's in cascade; thus the process has the same complexity as this algorithm. The method is valid for fractional orders varying from -1 to 1. Scaling factors for the FRT and Fresnel diffraction when calculated through the FFT...
متن کاملOptimal Fourier Transform Sampling Patterns
A model for optimizing the sampling of the Fourier Transform of a function is presented, together with a sequential semi-definite trust region strategy, and an implementation using the open-source solver CSDP. Numerical performance correlates with increasing dimension and decreasing number of non-zero function values. Simulation of an application to multi-dimensional NMR (used to study to prote...
متن کاملDiscrete Fourier Transform: Approach To Signal Processing
There are three different way to calculate DFT. First method is using formula of DFT or simultaneous equation. Second is Correlation technique and third one is using Fast Fourier Transform (FFT). First method is useful for understanding of basic idea of DFT, but it is not fit for practical and application purpose. In second method is based on detecting known waveform in another signal. It is us...
