In the early studies, when the double-pass system with the same diameter is used for the measurement of the human eyes aberration, the odd aberrations (such as coma) are cancelled because the odd aberrations of the two channels cancel each other out. A new model eye is proposed to verify whether the human eye′s odd aberrations are cancelled in double-pass system. Entrance pupil size (1-8 mm) is changed and exit pupil is fixed to 6 mm. The results shows that human eye′s odd aberration could be measured by a typical double-pass system, that is Hartmann wave-front sensor system. Human eye′s odd aberration is not related to the size of entrance pupil and exit pupil. Finally, the conclusion that the double-pass system does not cancel human eye′s odd aberration is obtained.
