Propagation properties of Gaussian beams passing through cat-eye optical system with misaligned lens

To analyze the influence of misaligned parameters of lenses on reflection properties of Gaussian beam, an approximate analytical expression of the output field distribution for Gaussian beam passing through a misaligned optical system with misaligned lenses were derived using approximate expression of the hard-edge ellipse aperture function and generalized diffraction formula. The result shows that influence of transverse displacement of a lens on the property of reflection beam is more notable than angle displacement. This method is helpful for the analysis of the transmission property of Gaussian beams.
