In order to obtain tomographic image of tissue

a confocal endscopic imaging system is established

its axial and lateral resolution has been measured and analyzed

and its application in pig skin has been investigated. First

based on the requirement of system

principles and configuration of system are presented. Then the theoretical values of spatial resolution are shown in confcoal endoscope. Finally

the system is tested

and the reason for difference between measuring date and theoretical value is illuminated. Experimental results indicate that its axial and lateral resolution is respectively 10 and 1.9

and it can be used to obtained tomographic image in pig skin.
