Abstract

Although joint Fourier transform processor is effective for the application to correlation operation, it can also be used as a generalized coherent image processor. In this paper we shall show that blurred photographic images due to linear motion can be restored with a joint transform processor. The major advantage of using the joint transform processor (JTP) for the image deblurring must be the avoidance of spatial filter synthesis. In other words, the deconvolution function for the image deblurring can be directly implemented at the input plane of a JTP, and the difficulty caused by the singularities of an inverse filter can be avoided. To generate a bipolar deconvolution function, we have encoded two sets of π phase shifted sinusoidal grating of the same spatial frequency. Computer simulation for restoration of linear-motion-blurred images are given to test the feasibility of the scheme.
