Paper Abstract

The optical transfer function (OTF) can be calculated from the design data, but their calculations have so far mainly restricted to the cases where the image forming wavefront is of uniform amplitude. In practice, this is not always the case, because the real amplitude can vary according to a polynomial in the pupil coordinate, which will be analogous to the wavefront aberration polynomial, and can vary with a radial gaussian distribution as in the intensity distribution across a laser( 1?eam Recently, a considerable amount of work has been carried out about this problem But the mathematical difficulties of evaluating the OTF in the general cases of an aberrated optical system with any kind of transmission function in exit pupil have limited the analytical results obtained in this field.
