Optimization of resolution in confocal imaging system

摘要：

The signal intensity is derived firstly on the basis of point spread function. Then the effect of pinhole radius on resolution is discussed for different central obstruction rate εε. According to the simulated plots, the optimum relationship of axial resolution to pinhole radius and central obstruction rate. εε is proposed. Finally the confocal imaging system is designed and established. The axial response is measured for different pinhole radius. Experimental results agree well with theoretical analysis. The in-focus images of bar target is obtained by the confocal imaging system which shows good performance
