Optical design of arthroscope based on gradient refractive index lens

  • 摘要: 关节镜是一种用于观察关节内部结构、诊治关节疾患的内窥镜。利用梯度折射率透镜质量轻、体积小、像质好的优点,运用Zemax软件设计了一款结构简单的关节镜光学系统,可用于1/10"CCD关节内窥镜成像。系统具有60视场角,F数为6, 工作距离从~5 mm,各视场的调制传递函数(MTF)在125 lp/mm时达到0.2以上,分辨率达到4 m,且各组态点列图均小于艾里斑半径。光学结构总长204 mm,最大镜头口径小于4.6 mm,根据关节镜的使用特点,系统满足使用要求。
    Abstract: Arthroscope is a kind of optical device which can observe the internal structure of our joints, as an endoscope to make a diagnosis and give treatment to the joint. The gradient refractive index(GRIN) lens has many merits such as light weight,small volume and good image quality, according to which a optical system with simple structure was designed with Zemax for-1/10"CCD arthroscope. The system has 60 field of view and the F number is 6, the working distance is ~5mm. The value of modulation transfer function (MTF) is more than 0.2 at 125 lp/mm, the resolution of the system is up to 4 m, the spot diagrams of all configurations are smaller than Airy disk. The total track is 204mm, the biggest caliber is less than 4.6mm. According to the characteristics of arthroscope,the system meets the requirement.
