摘要

A new high-performance laser scanning system is designed.In this system,a scanning arm consisting of a pentagonal prism and a scanning object lens is used to replace the traditional F6 lens,and a circular imaging plate transmission mechanism is specially designed in order to meet the requirement of the scanning arm.At the same time,the stimulation fluorescence can be obtained by the scanning arm.Some main factors that influence the spatial resolution and the performance of the laser scanner system are analyzed, and the analysis results are presented,which is helpful for further optimization design of the system. Experimental results indicate that the images obtained by the system have good visual effects and can meet the requirements of industrial inspection.
