摘要： An HMD apparatus includes an image source, a light guiding element, a first modulating element, and a second modulating element. The image source provides an image beam. The light guiding element is arranged on a transmission path of the image beam to transmit the image beam. The light guiding element has a first surface and a second surface opposite to each other. The image beam undergoes total internal reflection at the first surface and is emitted from the second surface. The first modulating element is arranged on one side of the first surface of the light guiding element and configured to adjust a transmittance of an ambient beam. The light guiding element is arranged between the first and second modulating elements, and the second modulating element is configured to adjust a focus position of the image beam. The HMD apparatus may improve wearing comfort and achieve good display effects.

摘要： 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. After the first and the second sub image beam are emitted from the second birefringent layer, a transmission path of the first and the second sub image beam are offset from each other by an offset distance, thereby improving resolution of an image to be viewed.
