Abstract

Embodiments of the present application provide a lens, a projector, and a near-eye display system. The lens is used to receive a fiber scanning signal sent by a display and modulate the fiber scanning signal, and the lens includes a first lens, a second lens arranged in sequence along the optical axis Two lenses, a third lens, a fourth lens and a fifth lens, the first lens is used for condensing or diverging the optical fiber scanning light signal emitted by the display to form the first transmitted light signal, and the second lens is used for condensing the first transmitted light signal to form the second transmitted light signal, the third lens is used to diverge the second transmitted light signal to form the third transmitted light signal, the fourth lens is used to diverge the third transmitted light signal to form the fourth transmitted light signal, the fifth lens For converging the fourth transmitted light signal to form the fifth transmitted light signal, the lens of the embodiment of the present application can modulate the optical fiber scanning signal sent by the display, so as to solve the problem that the curved image generated by the optical fiber scanning is unclear after projection.

Description

technical field [0001] The present application relates to the technical field of display projection, and in particular, to a lens, a projector and a near-eye display system. Background technique [0002] With the continuous development of augmented reality technology, head-mounted augmented reality devices such as smart glasses or smart masks are widely accepted and applied by users. [0003] The augmented reality device usually includes a projector, which can generate a virtual image, wherein the projector can generate a virtual image through the display mode of optical fiber scanning. Since the optical fiber scanning method is to control the scanning optical fiber to perform regular vibration, the light beam is incident. Therefore, the vibration of the scanning optical fiber causes the optical fiber scanning image source to be a curved surface, and the curved image is easily enlarged after projection, resulting in the problem of unclear imaging.
