1. An imaging system comprising:
a first reflective display configured to provide a first image beam;
a second reflective display configured to provide a second image beam, wherein the second reflective display has the same pixel configuration as the first reflective display; and
a light combining element disposed on transmission paths of the first image beam and the second image beam, wherein the light combining element has a light combining surface, and positions of the first image beam and the second image beam reflected on the light combining surface by pixels in corresponding positions in the first reflective display and the second reflective display are dislocation, wherein the light combining element comprises a first prism, a second prism, a third prism, and a polarizing light combining/splitting layer, the second prism is disposed between the first prism and the third prism, the polarizing light combining/splitting layer is disposed between the second prism and the third prism, and the first image beam passing through the polarizing light combining/splitting layer and the second image beam reflected by the polarizing light combining/splitting layer pass through the second prism and the first prism in sequence.
