Claim 0:
1. An augmented reality display device comprising:
a projection source module comprising a projection source;
a first optical path module comprising a first beamsplitter and a first reflector; and
a second optical path module comprising a second beamsplitter and a second reflector,
wherein the first beamsplitter and the second beamsplitter each comprise a beamsplitter substrate, and the first reflector and the second reflector each comprise a reflective film,
wherein virtual image light emitted from the projection source module and carrying virtual image information passes through the first optical path module first, in which the virtual image light is reflected at least twice and transmitted at least once by means of the first beamsplitter and the first reflector, then enters the second optical path module, in which the virtual image light is transmitted at least once and reflected at least twice by means of the second beamsplitter and the second reflector, and enters a human eye eventually, wherein the first reflector of the first optical path module and the second reflector of the second optical path module have first and second optical axes, respectively, and the first and second optical axes intersect a beamsplitting side of the first beamsplitter and a beamsplitting side of the second beamsplitter at two points, respectively, wherein a principal axis passes through the two points, wherein the second beamsplitter of the second optical path module is configured such that its beamsplitting side forms a first angle a with the second optical axis of the second reflector and forms a second angle β with the principal axis, wherein a range of the angle α is between β-10° and β+10, and
wherein scene light from a real scene enters the human eye through the second optical path module.
