Abstract :
The multi-dimensional information encoding is introduced as a means of displaying Fourier spectrums of signal, and an information encoding and displaying algorithm is proposed in this paper. It can be used in Fourier spectrum display and analysis of two-dimensional (2-D) image, and a 4-D hole-spectrum, i.e. first spatial frequency, second spatial frequency, magnitude and phase plot, of 2-D image is obtained. An experimental display system is developed, and the hole-spectrums of the 2-D images based on the multi-dimensional information encoding are analyzed. The results show that the hole-spectrum of the 2-D image based on the multi-dimensional information encoding are able to represent the details of the 2-D image magnitude and phase characteristics in the spatial frequency domain.<>
