摘要： In an embodiment, an off-axis hologram is provided. The off-axis hologram creates two, conjugate images which are on either side (off-axis) of the 0-order beam. A Multiple Beam Grating (MBG) is used to both duplicate the conjugate images and to redirect the images along the axis. The 0-order beam is blocked before or at the MBG. The MBG projects the images onto a 3D surface, such as a person's face.
