Influence of Detector on Resolution in Confocal Imaging System
共聚焦成像 高分辨率 点扩展函数 半高宽 Confocal imaging High resolution Point spread function (PSF) Half width at half maximum (HWHM)
摘要
基于点扩展函数,推导出共焦系统的成像公式,模拟了探测器尺寸对分辨率的影响,并提出最佳针孔半径.为验证理论分析,设计并建立了一套共焦系统,测量了不同针孔时的轴向响应,并得到了鉴别率板的共焦和离焦像.
Abstract
The imaging equations are derived based on point spread function,the influence of detector on resolution is simulated,and the optimum pinhole radius is proposed. To demonstrate the theoretical calculation,the confocal imaging system is designed and established. The axial response is measured for different pinhole,and the in-focus and out-of-focus images of bar target are obtained with the confocal system.
