Abstract: The application provides an augmented reality display device comprising a projection source module and an optical path module, the projection source module comprising a projection source (12) and a beam shaping element (14) which are integrated into a unitary piece, and the optical path module comprising a beamsplitter (20) and a reflector (60), wherein virtual image light (VL) emitted from the projection source (12) and carrying virtual image information is emitted out of the projection source module after being shaped by the beam shaping element (14), projected onto the beamsplitter (20) first, then reflected onto the reflector (60) by the beamsplitter (20), then reflected by the reflector (60), and enters a human eye (E) eventually, and scene light (AL) carrying real scene information enters the reflector (60) from an outside of the reflector (60), and is transmitted through the reflector (60) and the beamsplitter (20) into the human eye (E). The application also provides a wearable augmented reality system comprising the augmented reality display device and the projection source module for the augmented reality display device.

Abstract: The disclosure relates to an optical system for an augmented reality apparatus, comprising: an image projection source; and a polarizing beam splitter. The polarizing beam splitter is arranged such that light emitted from the image projection source is able to be non-perpendicularly incident on the beam splitting side and be at least partially reflected. The polarizing beam splitter is configured such that a polarized light component passes through the polarizing beam splitter and is transmitted through the transmission side thereof, and a polarized light component is reflected from the beam splitting side. The optical system also comprises a polarizer disposed between the image projection source and the polarizing beam splitter, and the polarizer is configured to allow polarized light, whose polarization is in the second direction, to be transmitted therethrough and polarized light, whose polarization is in the first direction to be absorbed.

Abstract: The disclosure relates to an augmented apparatus, and an optical system and a semi-reflector for the same. The optical system comprises: an image source; a beam splitter, the beam splitter having a beam splitting side adjacent to the image source and a transmission side facing away from the image source; and a semi-reflector, the semi-reflector being arrange adjacent to the beam splitting side and being downstream of the beam splitting side in an optical path along which light emitted from the image source is reflected by the beam splitting side, the beam splitter being arranged such that the light emitted from the image source is able to be at least partially reflected by the beam splitting side towards the semi-reflector, wherein the semi-reflector comprises a substrate and a semi-reflective film on a distal surface of the substrate. According the present application's technical means, the design freedom of the whole optical system can be increased and the field of view can be enlarged, which facilitates the final imaging result in the human eye.
