摘要
An analysis of the Strehl ratio and the optical transfer function as imaging quality parameters of optical elements with enhanced focal length is carried out by employing the Wigner distribution function. To this end, we use four different pupil functions: a full circular aperature, a hyper-Gaussian aperature, a quartic phase plate, and a logarithmic phase mask. A comparison is performed between the qualty parameters and test images formed by these pupil functions at different defocus distances. [SO740-3232(00)00605-0].
