Diffraction effects of a focal-plane slit shutter and its interaction with uniform linear image-motion.
A general expression for the exposure transfer function of a photographic system employing a focal-plane shutter is derived which includes the effects of uniform, linear image-motion. The results show that the modulation transfer function (MTF) of such a system is upper bounded by the product of the diffractionlimited optical MTF and a term strongly coupling the shutter and motion effects. The coupling of these effects results in a general solution dependent upon the size and shape of the pupil and the aberrations of the optical system.
