Sidelobe suppression of the point-spread function in annular-pupil optical systems.
New optical configurations suppressing sidelobes of point-spread functions in annular-pupil transmission optical systems are proposed for both one- and two-dimensional suppressions. In both optics, a point source and a one-dimensionally apodized pupil are combined. For two-dimensional suppression, the source and the pupil are rotated synchronously and its point-spread function is synthesized with time accumulation. The optical transfer functions of the two optics are theoretically derived.
