Title:
WAVEGUIDE LENS AND AUGMENTED REALITY GLASSES
Document Type and Number:
WIPO Patent Application WO/2021/098744
Kind Code:
A1
Abstract:
A waveguide lens (1), comprising a waveguide substrate (11), and a functional area (13) arranged on a surface of the waveguide substrate (11) and composed of gratings. Incident light emitted from a light source (12) is coupled into the waveguide substrate (11) by means of the functional area (13), and then transmitted to the functional area (13) by means of the waveguide substrate (11) and coupled out; the waveguide substrate (11) is curved, so as to increase the angle of total reflection of the incident light in the waveguide substrate (11). Augmented reality glasses, comprising the waveguide lens (1). The incident light emitted from the light source (12) is coupled into the waveguide substrate (11) by means of the functional area (13), and then transmitted to the functional area (13) by means of the waveguide substrate (11) and coupled out; the waveguide substrate (11) is curved, so as to increase the angle of total reflection of the incident light in the waveguide substrate (11) to increase the field of view.
