Title:
ROTATING ZOOM LENS SYSTEM AND METHOD FOR REALIZING SAME
Document Type and Number:
WIPO Patent Application WO/2019/024536
Kind Code:
A1
Abstract:
Provided are a rotating zoom lens system and a method for realizing the same. The rotating zoom lens system comprises a first lens assembly (1), a second lens assembly (2), and a liquid crystal module (3). An optical axis of the first lens assembly (1) and an optical axis of the second lens assembly (2) are arranged on the same straight line. A focal length of the stacked first lens assembly (1) and second lens assembly (2) changes with a change in relative angles of the first lens assembly (1) and second lens assembly (2). The liquid crystal module (3) is installed at one side of the first lens assembly (1) or one side of the second lens assembly (2). The rotating zoom lens system performs zooming by changing relative angles of lens assemblies without having to adjust a distance between the lens assemblies, such that the system has a compact size, can be manufactured easily, and is applicable to the field of optical instruments.
