Abstract

The purpose of this study is to develop a small diameter (less than 1 mm) and high resolution endoscope. This probe consists of single optical fiber which is fixed a Ni tube and photo-fabricated metal saddle-shaped coils and solenoid coil which is fabricated by coiling machine. The optical fiber which is fixed a Ni tube is inserted into coil. When an alternating current supplies to the driving coils, the Ni tube is vibrated by magnetic force one dimensionally. With the assist of the magnetic force by additional solenoid shaped assist coils which are located in frontside and backside of the saddle-shaped coil, the vibration amplitude of the fiber is increased. The 1 mm diameter probe has been fabricated, and fiber vibration amplitude increase was confirmed.
