Paper Abstract

The analysis of shadow casting by fine grids is extended to include the effects of diffraction. The transfer function of an incoherently illuminated 'pupil' grid is derived and shown to equal the autocorrelation of a modified pupil. Achromatic image casting properties having no geometric analogue are predicted and their application to a displacement transducer is described.
