  • Field curvature virtual image display system
    Patent number: 10627629
    Abstract: A field curvature virtual image display system applicable to a projection lens set comprises: an image source disposed in a partial region of an objective plane of the projection lens set; a first imaging group having a front lens group and a back lens group; and a second imaging group having a partial reflection and partial transmission surface and an antireflection surface and functioning as an image combiner. In a field curvature virtual image display system system, the objective plane is imaged as a virtual image surface with a specific field curvature type to generate an including angle between the optical axis of the first imaging group and the optical axis of active virtual image.
