摘要

摘要:为了实现穿刺过程中的精准定位，设计研制了一款视场角为90°，焦距为0.67 mm的高分辨率可视穿刺针光学系统。为使光学系统的光轴垂直于穿刺针的倾斜刃面，利用反射棱镜对光束进行转折，实现45°视向角。光学系统采用反远结构，并对初始结构参数的计算公式进行推导。经过优化设计后，系统成像质量接近衍射极限，最大光学元件尺寸小于1.5 mm。利用研制的光学系统和微型CMOS图像传感器，装配完成了一款直径为4 mm的可视穿刺针。对该可视穿刺针分别进行调制传递函数(MTF)测试和成像试验，测试结果表明，研制的光学系统具有较好的成像质量，物方分辨率优于18.03 lp/mm，能够实现清晰成像。

Abstract:In order to realize accurate positioning during the puncture surgery, a high-resolution optical system with a 90° field of view and 0.67 mm focal length is designed and developed for the visual puncture needle. A 45° viewing angle is chosen to make the optical axis perpendicular to the inclined edge surface by using a reflection prism. The retrofocus structure is used and the formulas for the initial structure parameters calculation are derived. The imaging performance of the optimized system is nearly diffraction-limited and the maximum size of the optical component is less than 1.5 mm. The optical system is developed, and it is assembled in a 4 mm diameter puncture needle with a miniature CMOS image sensor. The assembled visual puncture needle is evaluated with the Modulation Transfer Function (MTF) measurement and the imaging experiment. The measurement results show that the imaging quality of the optical system is good and its object-space resolution reaches 18.03 lp/mm, thus it can realize the requirement for high-resolution imaging.
