Abstract: The invention provides a see-through head-mounted display, including: an inner optical mechanism covered by a nontransparent housing having an opening and providing an image beam from the opening; and an outer optical mechanism including an outer polarizing beam splitter guiding the image beam from the opening and an environment beam to the same direction. The inner optical mechanism includes at least a mirror and a driving motor. The mirror reflects the image beam to make the image beam incident to the outer optical mechanism. The driving motor moves the mirror to vary the image distance from the mirror.
