Abstract
The fast Fourier transform is used in two-dimensions to calculate the apodizing effect of a center opening pupil shutter. Two shutter models are investigated and compared, a circular shutter with diameter a function of time, and a five-bladed leaf-type shutter. The influence of shutter shape, defocus, and third and fifth order spherical aberration on the time-averaged optical transfer function is investigated. The results indicate that there is only a small effect on resolution and depth of focus due to shutter motion in a well corrected optical system.
