<p><P>PROBLEM TO BE SOLVED: To transmit light with high accuracy and to acquire information on an object by a simple construction. <P>SOLUTION: An actuator provided in an endoscope tip portion vibrates a tip portion 12P of an optical fiber in a spiral manner. Further, a light refraction portion 12T is provided in the optical fiber 12 behind the actuator 16 and slope surfaces 12X and 12Y are formed on a cladding 12B. A plurality of photo sensors 14 are provided around the optical fiber 12 behind the light refraction portion 12T, a resin 19 having refractive index relatively larger than that of the cladding 12B is filled between the photo sensors 14 and the actuator 16. The reflected light that progresses in the cladding 12B exits from the slope surface 12X and is made incident to the photo sensors 14. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
