Three-dimensional optical Fourier transform and correlation.
نویسنده
چکیده
Optical implementation of a three-dimensional (3-D) Fourier transform is proposed and demonstrated. A spatial 3-D object, as seen from the paraxial zone, is transformed to the 3-D spatial frequency space. Based on the new procedure, a 3-D joint transform correlator is described that is capable of recognizing targets in the 3-D space.

Optical 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 کاملThree-dimensional Image Watermarking Using Fractional Fourier Transform
In this paper, we propose an optical image watermarking scheme using the fractional Fourier transform. A two-dimensional watermark is encrypted using a double random fractional order Fourier domain encoding technique. The encrypted image is watermarked into a three-dimensional intensity image reconstructed from a real in-line digital hologram. The watermark is recovered by applying the correspo...
متن کاملSecond-order fractional Fourier transform with incoherent radiation.
Based on the coherent optical theory, we extend the fractional Fourier transform of first-order correlation to a fractional Fourier transform of second-order correlation. An optical system for implementing a second-order fractional Fourier transform was designed. As a numerical example, we investigate the second-order fractional Fourier transform for a single slit.

Joint Fourier transform correlation is an analog optical signal processing technique capable of comparing several two-dimensional images. We show that selected spectral domain binary thresholds, obtained through simulation, signiicantly improve the performance of an optical implementation of the joint transform correlator. In doing so we establish empirically the existence of well deened optima...
متن کاملCompression of digital holograms for three-dimensional object recognition
In this paper we present the results of applying data compression to a three-dimensional object recognition technique based on phase-shift digital holography. Industry-standard lossless data compression algorithms were rst applied. Next, lossy techniques based on subsampling, discrete cosine transformation, and discrete Fourier transformation were examined. We used normalized cross-correlation ...
