Abstract
Thus far optical imaging of the finger joints is limited to only one joint at a time. We have developed a CCD-based system that can image a whole finger, covering multiple joints. We show that the two joints of a volunteer's index finger can be imaged clearly and concurrently. The comparison of the optical images with the x-ray image of the same finger indicates that the recovered size of the whole finger, the bones and the two joint spaces are consistent with the findings from the x-ray. This study demonstrates a practicable system for full finger imaging and indicates the possibility of full hand imaging if a fast laser source scanning subsystem is integrated with the system.
