Zusammenfassung:	An AR optical system includes a depth-of-field separation structure corresponding to an image source, configured to convert light rays emitted from the image source into a plurality of light beams with different depths of field; a convergent lens located on an emergent light path of the depth-of-field separation structure, and configured to receive and shape the plurality of light beams with different depths of field; a first semi-transmitting semi-reflecting mirror located on a side, away from the depth-of-field separation structure, of the convergent lens, and configured to reflect the plurality of shaped light beams with different depths of field towards a set direction; a concave mirror having a preset transmission-reflection ratio configured to reflect and converge the plurality of light beams with different depths of field and then make the light beam incident to a set observation position after passing through the first semi-transmitting semi-reflecting mirror.
