Document Type and Number:
WIPO Patent Application WO/2021/253152
Kind Code:
A1
Abstract:
A lens (10) has an incidence axis (101), and comprises a lens element (110). The lens element (110) comprises at least two sub-lenses (1111, 1112). The sub-lenses (1111, 1112) are non-rotationally symmetric structures. Each of the sub-lenses (1111, 1112) comprises an effective light transmission portion (1101). Any two effective light transmission portions (1101) of the lens element (110) are rotationally symmetric relative to the incidence axis (101). The effective light transmission portions (1101) of the lens element (110) allow an incident light beam to pass therethrough so as to present mutually separate formed images (1051, 1052) at an image side of the lens (10). The number of formed images (1051, 1052) is equal to the number of sub-lenses (1111, 1112) of the lens element (110).
