ABSTRACT:
A head mounted display includes two imaging apparatuses and at least one optical compensator. The imaging apparatuses can form two virtual images respectively in front of two eyes of a user. The optical compensator can modulate wavefront of the image beams of the virtual images so as to adjust the positions of the virtual images. In this manner, the positions of the two virtual images can be adjusted to substantially coincide with each other. The present invention also provides an image adjustment method for a head-mounted display.
