    摘要: An object distance adjusting apparatus includes: an object distance adjusting portion, for fixing an optical device and adjusting a position of the optical device relative to an object image display portion; a limiting portion, for fixing the object image display portion and limiting a limit position of the object distance adjusting portion relative to the object image display portion; and a connecting and fixing portion, which is on a side of the limiting portion away from the object distance adjusting portion and is connected to the object distance adjusting portion, for fixing the limiting portion, the optical device and the object image display portion. Virtual display glasses include an optical device, an object image display portion, and the object distance adjusting apparatus, which can fix the optical device and the object image display portion, and adjust the position of the optical device relative to the object image display portion.

    摘要: An optical system includes at least one first display module, at least one second display module, and a first optical element. The first optical element includes a first light incident surface, a second light incident surface, and a viewing surface. The first light incident surface is configured to transmit imaging light emitted from the at least one first display module into the first optical element and refract it onto the second light incident surface. The second light incident surface is configured to transmit imaging light emitted from the at least one second display module into the first optical element and refract it onto the viewing surface, and reflect the imaging light transmitted into the first optical element through the first light incident surface onto the viewing surface. The viewing surface is configured to transmit the imaging light emitted from all display modules to a human eye.

    摘要: An optical module includes a lens barrel main housing, at least one dimming lens installed in the lens barrel main housing, a first cover assembly and a second cover assembly. Opposite ends of the lens barrel main housing are provided with a first opening and a second opening. The inner circumferential wall of the lens barrel main housing is provided with at least one limiting portion. Each dimming lens abuts against a limiting portion in the preset direction. The first cover assembly is arranged on the first opening and includes a light source configured to emit image beams to the at least one dimming lens. The second cover assembly is arranged on the second opening and includes a transparent component being capable of transmitting the image beams passing through the at least one dimming lens to an outside of the lens barrel main housing.
