中文摘要	the axial intensity distribution and focal depth of an apoclized focusing optical system are theoretically investigated with two kinds of incident light fields: a uniform-intensity-distribution beam and a gaussian beam. both a low-numerical-aperture and a high-numerical-aperture optical system are considered. numerical results show that the depth of focus can be adjusted by changing the geometrical parameters and transmissivity of the apodizer in the focusing optical system. when a gaussian beam is employed as the incident beam, the waist width also affects the depth of focus. the tunable range of the focal depth is very considerable.
