英文摘要	in a previous letter [opt. lett. 33, 1171 (2008)], we proposed an improved logarithmic phase mask by making modifications to the original one designed by sherif. however, further studies in another paper [appl. opt. 49, 229 (2010)] show that even when the sherif mask and the improved one are optimized, their corresponding defocused modulation transfer functions (mtfs) are still not stable with respect to focus errors. so, by further modifying their phase profiles, we design another two logarithmic phase masks that exhibit more stable defocused mtf. however, with the defocus-induced phase effect considered, we find that the performance of the two masks proposed in this letter is better than the sherif mask, but worse than our previously proposed phase mask, according to the hilbert space angle.
