Abstract: An imaging method of a head-mounted display and a head-mounted display are disclosed. The method includes, but is not limited to: detecting a wavefront of a beam emitted by the head-mounted display through its optical system; acquiring a position of a visual axis of a human eye; calculating a deviation between the visual axis of the human eye and an optical axis of the optical system; and adjusting a wavefront incident to the human eye according to the deviation, so that a correspondence between the wavefront incident to the human eye and the visual axis is consistent with a correspondence between the wavefront of the beam emitted from the optical system and the optical axis.
