宽光谱下大视场高分辨齐焦关节内窥镜设计
Design of a wide-spectrum,large-field,high-resolution and parfocal arthroscope
摘要
Abstract
To enhance the imaging performance of arthroscopes in clinical surgery and broaden their poten-tial for clinical applications,a wide-spectrum arthroscopic optical system featuring a large field of view,high resolution,and parfocal imaging capability in both visible and near-infrared bands was designed.The object-ive lens uses a high optical power negative lens to compress the chief-ray angle and reduce the optical path difference between off-axis and on-axis rays.Through conjugate aperture imaging,an equivalent virtual stop is formed inside the turning prism,which allows the system to maintain both high transmission efficiency and high image quality under a limited aperture.The relay lens adopts a near-symmetric structure,and by distrib-uting optical power and Abbe numbers appropriately,it effectively suppresses the accumulation of axial chro-matic aberration across the broad spectral range,thereby achieving parfocal imaging.Tolerance analysis shows that the system has good manufacturability and assembly feasibility.Experimental results verify that the designed wide-spectrum arthroscope achieves parfocal imaging in the visible and near-infrared bands with a 95° field of view,and angular resolutions of 4.34 C/(°)and 2.74 C/(°),respectively.The optical sys-tem provides a feasible solution for achieving low-cost,high-performance fluorescence arthroscopy and has significant application value.关键词
