Patent number: 10989968Abstract: An optical element configured to allow an image beam passing through is provided. The optical element includes a first and a second birefringent layer and a gas layer between the first and the second birefringent layer. An extension direction of the gas layer is inclined with respect to an extension direction of the optical element, wherein the image beam passes through the first birefringent layer, the gas layer and the second birefringent layer in sequence. A first and a second sub image beam having different deflection angles are generated from the image beam when the image beam enters the gas layer.
