Abstract:

A complete description of motion degradation in linear incoherent, optical systems is presented. Given a mechanical description of motion between object and imaging system, an equivalent two-dimensional linear system is derived which includes all the motion degradation effects. The system is space-variant in the general case in that each point in the object intensity distribution is blurred by an amount which varies with position to form the recorded image. A number of examples are discussed including the space-invariant point-spread functions of planar object-image translation and space-variant cases of rotational motion and coordinate distortions. The effects of systems in cascade are treated and the motion and point-spread functions for general aerial imaging systems are derived in detail. Several a posteriori methods are given for restoring and enhancing images blurred by linear space-variant and invariant operations. Author
