Abstract

Rotation blur cannot be described by a convolu-tion in x-y space, as, e.g., linear motion blur. Hence inverse filtering (deconvolution) in x-y is not possible, the system to be inverted is shift-variant. By modelling the recording process (e.g. on photographic material) in three dimensions (x-y and t), however, the blurring process can be described as a convolution and a multiplication. The 3D functions involved can be handled by a coherent-optical processor by means of sequence representations. Hence deblurring becomes essentially a sequence deconvolution. The sequence deconvolution point response is discussed and experimental re-sults for blur simulation and deblurring are shown.
