Propagation Properties of Oblique and Off-Axial Gaussian Beams Passing Through Cat-Eye Optical Lens
The propagation equations for oblique and off-axial Gaussian beams passing through cat-eye optical lens are deduced by using the theory of matrix optics and expanding the aperture function into a finite sum of complex Gaussian functions. By numerical computation, the laws governing the variation of the intensity distribution of the cat-eye reflected light with the obliquity factor and the off-axis magnitude are given. The result shows that the intensity distribution of the cat-eye reflected light under oblique condition has asymmetric aberrance, and the distribution rules at small and large different obliquity factors differ greatly. Furthermore, the feasibility of cat-eye effect reflected light used in the active laser detection system is determined by the obliquity factor and the off-axis magnitude.
