Abstract
Strongly magnified images of a periodic object can be obtained by using the Talbot effect. Two particular advantages are simplicity and compactness of the setup even for a high magnification ratio. First we recall the principle of self-imaging and the basic results derived by Rayleigh. These results were obtained from simplifying assumptions, which we show to be particularly unrealistic for high magnification ratios. A possibly more accurate and nevertheless practical approach is proposed.
