The present application provides a virtual image display apparatus. The virtual image display apparatus includes an image source configured to produce imaging illumination; an optical relay configured to receive the imaging illumination from the image source, and configured to transmit a detection light having an aberrated wavefront representing imaging distortion in a virtual image displayed by the virtual image display apparatus; a wavefront sensor configured to receive the detection light, and configured to detect wavefront aberration information from the detection light; and a wavefront correction processor configured to receive the wavefront aberration information from the wavefront sensor, and configured to adjust in real time the imaging illumination produced by the image source to reduce the imaging distortion in real time.
