1. A multi-image display apparatus comprising:
- a diffractive optical lens element having a focal length varying based on a wavelength and a polarization state of incident light;
an image forming device configured to form a first image comprising a first color image, a second color image, and a third color image; and
an optical system configured;
to transfer the first image and a second image to the diffractive optical lens element, the second image being transferred along a second optical path different from a first optical path along which the first image is transferred, andto offset chromatic aberration of the diffractive optical lens element by providing different optical path lengths for the first color image, the second color image, and the third color image.

Abstract
A multi-image display apparatus for augmented reality (AR) or mixed reality (MR) includes a diffractive optical lens element, an image forming device configured to form a first image including a first color image, a second color image, and a third color image, and an optical system configured to transfer the first image and a second image to the diffractive optical lens element, the second image transferred along a path different from a path of the first image. The optical system is configured to offset chromatic aberration of the diffractive optical lens element by providing different optical path lengths for the first color image, the second color image, and the third color image.

37. A multi-image display apparatus comprising:
-
a diffractive optical lens element having a focal length varying based on a wavelength of light; a first image forming device configured to form a first image comprising a first color image, a second color image, and a third color image; a second image forming device configured to form a second image; and an optical system configured to; provide the first color image having a first optical path length, a second color image having a second optical path length, and the third color image having a third optical path length, the first, second, and third optical path lengths being of different lengths; and to transfer the first image formed by the first image forming device and the second image formed by the second image forming device to the diffractive optical lens element, wherein the diffractive optical lens element is configured to focus the first color image, the second color image, and the third color image included in the first image on a same plane. - View Dependent Claims (38, 39, 40)
