Title:
ADJUSTABLE-FOCUS 3D OPTICAL ENDOSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/103524
Kind Code:
A1
Abstract:
An adjustable-focus 3D optical endoscope system, which relates to the technical field of 3D imaging and medical devices. An endoscope comprises: an endoscope tube (1.1), a dual-optical-path imaging lens group (2.1), which is arranged in the endoscope tube (1.1) and used for binocular image acquisition, a bi-telecentric relay lens group (2.2) for merging two optical paths into a single optical path, and an imaging sensor, which is used for receiving an image transmitted from the bi-telecentric relay lens group (2.2). The adjustable-focus 3D optical endoscope further comprises a focus adjustment assembly (1.2), which is connected to the bi-telecentric relay lens group (2.2). In the adjustable-focus 3D optical endoscope, a bi-telecentric relay system is used to merge the two optical paths into the single optical path, which simplifies a back-end system structure and ensures high-quality image transmission; and a focus adjustment structure is used to achieve high-definition imaging at different imaging distances.
