1. An optical imaging system, comprising:
a display assembly, adapted to output light corresponding to an image;
a lens assembly, adapted to enlarge the image;
a polarization converter, wherein the polarization converter includes a frequency-dependent polarization converter, configured to convert the light at a first frequency to a first polarization and convert the light at a second frequency to a second polarization; and
an aberration-correcting optical assembly, including a polarization-dependent planar optics assembly;
wherein the aberration-correcting optical assembly includes a diffractive optical element, providing deflection degrees for the light based on wavelengths thereof and providing positive and negative powers for the light based on the polarizations thereof.
