title: Bessel annular apodizers: imaging characteristics.
abstract: Apodizers with relatively high transmittance over an annular region of the exit pupil can reduce the sensitivity to defocusing and to spherical aberration [Opt. Lett. 11, 487 (1986)]. Here, we analyze the imaging properties (pupil functions, point spread functions, optical transfer functions, and Strehl ratios) of the Bessel type of annular apodizers. We also show some computer-simulated images, obtained with and without this kind of annular apodizer.
